Abstract

A quasi-3D model of a polymer electrolyte fuel cell is described. The model includes equations for the gas transport in feed channels and in porous layers, current conservation equations and Butler-Volmer expressions for the rates of electrochemical reactions. The model resolves catalyst layers and gives maps of parameters in a cross section of a cell equipped with long meander channels on both sides. As an example, the role of water management in the fuel cell operation is demonstrated. It is shown that near the inlet electroosmosis can noticeably dry out the anode catalyst layer and the adjacent bulk membrane, which leads to degradation of cell performance.
