COMSOL Multiphysics is a very helpful simulation software in our researches on both PEMFC and nanometer-sized electrodes. In the first part of our presentation, the influence of humidity and temperature to the performance of PEMFC are studied by simulating the MEA (membrane electrode assembly) in PEMFC. In the second part, models of different nanometer-sized electrodes, including spherical electrodes and disk electrodes, are developed so that we can get a deep insight to the behaviours of nanometer-sized electrodes. The flexibility of modules in COMSOL Multiphysics allows us to input our own equations easily, and the MATLAB interface is very useful in the data processing.
