Abstract
Temperature distribution of the proton exchange membrane fuel cell (PEMFC) takes a im?portant influence on the cells performance especially on current density, and the interdigitated flow field helps to enhance current density. The temperature distribution of PEMFC with interdigitated flow field was investigated, by simulation method at traverse direction, anode catalysis layer, mem?brane center and cathode catalysis layer, to obtain the rule of temperature distribution. The influences of current density variation on flow field temperature at the voltages of 0.4, 0.6, 0.8 V and the tem?perature differences of membrane at inlet and outlet channels, shoulders were investigated to obtain temperature distribution rules of membrane at the different voltages.
