5. (Invited) The Implications of Cation Clustering in Anion Exchange Membranes on Conductivity and Mechanical Properties

Author

Herring, Andrew M, Coughlin, E. Bryan, Liberatorre, Mathew W., Pandey, Tara P, Sarode, Himanshu N, Liu, Ye, Di Noto, Vito, and Vezzù, Keti

Abstract

Anion exchange membranes (AEMs) contain cations that act as dipoles. The dipoles interact with each other and give rise to clustering in the AEM and this clustering can affect the ionic conductivity and mechanical properties of the polymer. Polymers designed to have dispersed cations can, when wet, have their cations cluster as the material undergoes an order-disorder transition at some temperature at which the system has enough energy to reorganize. Clustering is often unavoidable in AEMs and imposes a limit on the increase in conductivity that can be achieved by increasing IEC. Above a certain IEC AEMs do not show increased ionic conductivity only increased swelling on exposure to higher RH. Understanding these phenomena is essential to designing high performance AEMs. Here we propose an AEM based on a scalable random copolymer with rapidly deployed photo-crosslinking to lock the morphology in place to avoid cation clustering.

6. Fundamental Studies of Alkaline Exchange Membranes towards Optimization in a Fuel Cell Environment

Author

Herring, Andrew M., Vandiver, Melissa A., Maes, Ashley M, Sarode, Himashu N, Coughlin, E. Bryan, Knauss, Daniel M., Yan, Yushan, Lindberg, Gerrick E., Knight, Christopher, Voth, Gregory A., Herbst, Daniel, Witten, Thomas A., and Liberatore, Matthew W.

Abstract

There is increasing interest in the alkaline exchange membrane (AEM) fuel cells as this device, if realized, could allow the use of inexpensive metal catalysts and the oxidation of a variety of convenient liquid fuels. While there have been some dramatic early achievements, there is still a need for a fundamental study of anion transport, cation stability and the formation of robust thin films in this area. We have undertaken a comprehensive study of anion transport and AEMs where theory is linked to well-defined model systems, both in solution and in the solid state, which are characterized using very careful environmental control such that the models can be validated and used predictively. We are also fabricating a number of structured copolymer AEMs that can be produced readily in large quantities, allowing us to understand film formation coupled with transport and stability.

Those based on perfluorinated backbones invite interesting comparisons with the analogous proton exchange membranes.
