Thermal management is critical for improving the performance of a proton exchange membrane fuel cell (PEMFC). Operation temperature can directly affect the saturated water vapour pressure and thus the water transport between the anode and cathode in PEMFCs. However, current researches on the effect of operation temperature on the performance are based on convenient design of a joint coolant flow channel for the anode and cathode. Consequently, the independent effect of the temperature on the anode or cathode is ignored. In this study, a single ...
