摘要：
A heat transport dynamic model of proton exchange membrane fuel cell (PEMFC) stack and the factors affecting stack temperature were considered. Neglecting cooling effect, the stack temperature increases quickly with the stack current, if the feeding gas rate of reactant is a little higher than one needed for the load. If the stack current is constant, with the increase of the feeding rate of reactants, the results also show that the stack temperature may transit to a stable region from an unstable one. Moreover, the simulation shows that it is desired to use a cooling system to keep the stack working steadily. The experimental data agree well with the simulation results.
