Solid Oxide Fuel Cells are regarded as a high-efficiency, low-environmental impact technology for power and heat generation. SOFCs based on proton-conducting electrolyte are one of the most attractive technologies, mainly due to their high efficiency in energy conversion and operation at the intermediate range of temperatures. The main objective of this paper is an investigation into the possibility of applying the reduced order model proposed by Milewski [1] to model proton-conducting Solid Oxide Fuel Cells. The reliability of the simulation results were verified with experimental data reported in the literature. It was shown that the reduced order model is valid for both ion-conducting SOFCs and proton-conducting SOFCs. [ABSTRACT FROM AUTHOR]

The article provides an overview of knowledge on how to model fuel cells using software which is oriented to system modeling. The overview covers several types of fuel cell such as SOFC, MCFC and PEMFC. Fuel cells were modeled using mainly three types of software, i.e. Aspen Hysys, Aspen Plus and Matlab. Based on our literature review, we decided to use Aspen Hysys to create a proton conducting SOFC model. Model construction is based on a reduced order approach that we published earlier. We used available experimental data to verify the model we created on. The results generated by the model and the experimental data were then subjected to an error analysis. Only two of all the articles found contained a set of information that was fit for the purpose of validating the model. The model maps the work of the proton conducting SOFC with high accuracy, i.e., an error of 0.01 V. • The methodology for model implementation in available software is reported. • The model represents an alternative approach for voltage prediction of a H + SOFC. • A validation process for the models implemented in Aspen Hysys/Excel is presented.

• An alternative approach for voltage prediction of a single cell H-SOFC has been developed. • Model is based only on physical, geometrical and material properties of the fuel cell. • A validation process is done. The aim of this study is to develop a new approach for modeling the voltage of H-SOFC. The proposed 0-D model collects electrochemical, thermal, electrical and flow parameters. The main aim is to have a combination of all cell working conditions in as a low number of factors as possible and to have factors that are relatively easy to determine. Various experimental data was collected and the results of the validation process are shown. Various fuel mixtures across relatively wide ranges of parameters were used to validate the model.
