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.
