In the development of more efficient and stable Polymer Electrolyte Fuel Cell (PEFC), it is important to propose the optimal operating condition and the optimal shape that can uniform the distribution of current density and relative humidity in a single cell. In this study, we improved the former model that is PEFC reaction and flow analysis model, and we developed the new model that includes the flow and heat transfer of cooling water. It could be used for real cell calculation in detail. Furthermore, we proposed the guideline for optimum operation condition and optimum component shape.
