Abstract

International audience; Solid dust particles from a few nanometers to centimeters can often be found in plasmas. This new species is at the origin of a wide variety of new plasma phenomena. These plasmas containing dust particles are called dusty or complex plasmas. They are encountered in many environments such as astrophysics, industrial processes, and fusion devices. Dust particles can come from regions in the plasma vicinity or can be formed in the plasma due to the presence of molecular precursors. These precursors can result from the presence of reactive gases (silane, methane, acetylene) or from material sputtering at the molecular level. Then, they initiate a complex succession of chemical and physical reactions, leading to the growth of dust particles. As long as precursors are available in the plasma phase, dust particle formation can be a cyclic phenomenon. Furthermore, as the dust particles are growing, they attach plasma free electrons, leading to a disturbance of plasma equilibrium when the dust particle density is high. New phenomena, like the occurrence of various instabilities are then observed. These behaviors seem to be present in many dusty plasmas created in different chemistries, experimental setups and conditions. In this presentation, we will discuss about these nearly universal phenomena and will principally focus on experiments related to dust successive generations and instabilities.

Abstract

International audience; A plasma polymerization process using a continuous glow discharge has been implemented for preparing proton conducting membranes from trifluoromethane sulfonic acid and styrene. The chemical and physical structure of plasma membranes has been investigated using FTIR and SEM. The films are homogeneous with a good adhesion on commercial gas diffusion layer (E-Tek®). Their deposition rate can be increased with increasing flow rate and input power. The thermogravimetric analysis under air of plasma polymers has showed a thermal stability up to 140 °C. Compared to the pulsed glow discharge studied in a previous paper, the continuous glow discharge has enabled to enhance the proton conductivity of membranes by a factor 3 (up to 1.7 mS cm−1). Moreover, the low methanol permeability (methanol diffusion coefficient down to 5 × 10−13 m2 s−1) of membranes has been confirmed by this study. In an industrial context, a reactor prototype has been developed to manufacture by plasma processes all active layers of fuel cell cores to be integrated in original compact PEMFC or DMFC.

Abstract

9 pages; International audience; Nanostructured platinum-carbon thin films were prepared by magnetron co-sputtering method for designing efficient catalytic thin films, like fuel cells electrodes. The in-depth morphology of composite films was studied using surface sensitive X-ray techniques (grazing incidence small-angle scattering and reflectivity), consolidated by electron microscopy investigations. This study elucidates the growth mode of co-sputtered platinum-carbon thin film: 2-nm-sized platinum clusters are growing in surrounding simultaneously growing carbon columns (20-nm diameter range). In particular, the platinum cluster growth and distribution in the plane of the substrate surface are driven by surface diffusion and coalescence phenomena. Finally, this anisotropic distribution of platinum clusters correlated to the textured morphology of carbon matrix leads to a catalytic thin film morphology very suitable for electrochemical processes in fuel cell electrodes.

Abstract

International audience; Co-sputtered Pd0.7Au0.3 catalyst and alternate sputtered Pd0.35Au0.3Pd0.35 and Au0.15Pd0.7Au0.15 materials were prepared by plasma deposition of Au and Pd atoms on a carbon diffusion layer. Atomic composition and metal loadings were evaluated from EDX and RBS, respectively. The low amount of metal deposited and the resulting low metallic film thickness made TEM and XRD characterizations difficult to perform, therefore, catalyst microstructures and surface compositions were determined from electrochemical methods and compared with data obtained with Pd/C, Au/C and Pd0.7Au0.3/C materials synthesized via the "water in oil" microemulsion method. The surfaces of co-sputtered Pd0.7Au0.3 and alternate sputtered Pd0.35Au0.3Pd0.35 and Au0.15Pd0.7Au0.35 materials are partly composed by PdAu alloy. The plasma sputtering method leads to more active bimetallic PdAu material than the wet chemistry method. Modification of palladium surface by gold atoms leads to increase the catalytic activity toward glycerol electrooxidation. The PdAu surface alloy composition has no significant effect on the catalytic activity, however, the presence of non-alloyed gold sites on the material surface leads to the enhancement of the catalytic activity. The mechanism seems to involve glycerol adsorption on palladium surface and hydroxyl species formation on gold surface leading to catalytic activity enhancement through the bifunctional mechanism.

Abstract

International audience; A PdPt (10 wt% Pt) catalyst is used to replace platinum at the cathode of a PEMFC MEA whereas pure palladium is used as the anode catalyst. The catalysts are deposited on commercial carbon woven web and carbon paper GDLs by plasma sputtering. The relations between the depth density profiles, the electrode support and the fuel cell performances are discussed. It is shown that the catalyst gradient is an important parameter which can be controlled by the catalyst depth density profile and/or the choice of electrode support. An optimised electrode structure has been obtained, which allows limiting the platinum requirement. Under suitable conditions of a working PEMFC (80°C and 3 bar absolute pressure), very high catalysts utilization is obtained at both electrodes, leading to 250 kW gPt-1 and 12.5 kW gPd-1 with a monocell fitted with a PdPt (10:1 weight ratio) cathode and a pure Pd anode.

Abstract

Poster; Poussières et plasmas cohabitent fréquemment. Les poussières sont souvent créées par le plasma lui-même, du fait de la présence de gaz réactifs ou par l'érosion des surfaces exposées au plasma. Ces plasmas poussiéreux se rencontrent à l'état naturel en astrophysique et dans les plasmas artificiels utilisés pour les applications industrielles ou pour la fusion thermonucléaire. Dans les plasmas de laboratoire (plasmas froids, basse pression), les poussières forment un nuage qui, sous l'effet de diverses forces, est généralement piégé dans la décharge. Ce nuage n'est pas homogène et une zone vide de poussières (void) apparaît au centre de la décharge. L'étude de cette zone est fondamentale car son existence soulève de nombreux problèmes expérimentaux et théoriques. Sa présence empêche tout traitement homogène du plasma et du nuage dans les modèles théoriques ou les simulations. Le void peut conduire l'expérimentateur à diagnostiquer l'absence de poussières s'il utilise par exemple des techniques de diffusion de la lumière dans cette zone. Le dépôt de poussières pour les applications industrielles est également modifié, le void entraînant des inhomogénéités. Le void est également le siège de nombreux phénomènes complexes: générations successives de poussières, instabilités non-linéaires, interfaces, ... Ces aspects seront abordés en insistant plus particulièrement sur les oscillations non-linéaires du void.

Abstract

Copyright 2010 by the American Physical Society This article is also available at http://link.aps.org/doi/10.1103/PhysRevLett.105.075002; International audience; In complex plasmas, the trapped dust particle cloud is often characterized by a central dust-free region (”void”). The void induces a spatial inhomogeneity of the dust particle distribution and is at the origin of many intricate unstable phenomena. One of this behavior is the so-called heartbeat instability consisting of successive contractions and expansions of the void. This instability is characterized by a strong nonlinear dynamics which can reveal the occurrence of incomplete sequences corresponding to failed contractions. Experimental results based on high-speed imaging are presented for the first time and underline this threshold effect in both the dust cloud motion and the evolution of the plasma light emission.

Abstract

Oral; In a plasma, dust particles acquire a negative charge. Thus, a high density of dust particles strongly reduces the free electron density and can drastically alter the plasma equilibrium leading to a wide variety of instabilities (as in electronegative plasmas). One of these instabilities concerns the dust-free region (void) often appearing in the center of the discharge. This void is maintained by two forces of opposite directions and a break in this equilibrium can lead to strongly nonlinear oscillations of the void size. In this presentation we analyze these low-frequency oscillations on the dust cloud and the plasma thanks to high-speed imaging. Correlations are made with the evolution of the discharge current which shows a nonlinear behavior similar to mixed-mode oscillations (MMOs) well- known in other fields like chemistry or neuronal science. We perform an analogy between MMOs in these fields and the ones we obtained. These MMOs are also highly studied through dynamical system theories which can provide a new approach for studying plasma instabilities.

Abstract

Ultra-low Pt content PEMFC electrodes have been manufactured using magnetron co-sputtering of carbon and platinum on a commercial E-Tek® uncatalyzed gas diffusion layer in plasma fuel cell deposition devices. Pt loadings of 0.16 and 0.01 mg cm−2 have been realized. The Pt catalyst is dispersed as small clusters with size less than 2 nm over a depth of 500 nm. PEMFC test with symmetric electrodes loaded with 10 μg cm−2 led to maximum reproducible power densities as high as 0.4 and 0.17 W cm−2 with Nafion®212 and Nafion®115 membranes, respectively. Keywords: Platinum, Solid polymer electrolyte, Fuel cell, Plasma sputtering deposition, Ultra-low platinum loading

Abstract

Ultra-low Pt content PEMFC electrodes have been manufactured using magnetron co-sputtering of carbon and platinum on a commercial E-Tek uncatalyzed gas diffusion layer in plasma fuel cell deposition devices. Pt loadings lower than 0.01 mg cm-2 have been realized. The Pt catalyst is dispersed as small clusters with size less than 2 nm over a depth of 500 nm. PEMFC test with symmetric electrodes loaded with 0.01 mg cm-2 led to maximum reproducible power densities as high as 0.4 Wcm-2 with Nafion 212. Replacement of platinum by palladium using plasma sputtering methods was also realized by preparing MEAs composed of 0.01 mgPd cm-2 for the anode and 0.01 mgPd cm-2 + 0.001 mgPt cm-2 for the cathode and Nafion 212 membrane. Power density as high as 250 mW cm-2 were achieved at 80°C, which corresponds to a specific power density of 250 kW gPt-1.
