Simulation on the Cooling Effect of Proton Exchange Membrane Fuel Cell

Abstract:

The cooling of proton exchange membranes fuel cell (PEMFC) is one of the crucial components in the heat management of a fuel cell. This paper presents three cooling channels of PEMFC: linear, serpentine and heat pipe. The cooling geometric models are proposed for the three cooling channels, respectively, and the corresponding temperature distributed diagrams are derived under steady state by SINDA/FLUINT. From the simulation, the linear cooling channel of PEMFC renders local overheating inside the cell under the same conditions, obviously. It is also observed that the serpentine cooling channel ensures the uniformity of cell temperature, whereas the change of channel diameter is not able to adjust the radiating performance effectively. Extensive simulation results show that the heat pipe cooling channel not only outperforms the other cooling channels in radiating performance, but also provides a remarkable environmental factor.
