Abstract
A two-dimensional steady state numerical model for high temperature polymer exchange membrane fuel cells based on Nafion212/SiO2 composite membrane was developed. Finite element method was used to solve electrochemical kinetics coupled with flow, multi-component transport, charge balance and energy conservation. The model-predicted fuel cell polarization curve was compared with the published experimental result and a good agreement was found. The effects of the structure parameters of the catalyst layer including Pt/Carbon ratio and Pt loading on the performance of high temperature polymer exchange membrane fuel cells were evaluated.
