Abstract

The over-potentials in a fuel cell due to ohmic losses and concentration polarization can be reduced if the gas delivery field and the current collection system are well designed. To obtain such a substantial understanding for designing the gas delivery and current collection system, this study proposed a model to theoretically analyze the current collection process, and finally a method and tool of optimization for scales of gas channels and current collection ribs is presented. The analysis found that small current collectors and collection area is advantageous for getting high power density in both PEMFCs and SOFCs. Copyright @ 2006 by ASME.
