FLOW FIELD PLATES IN FUEL CELLS |
摘要 |
A method of producing a flow field plate for a fuel cell comprises over-profiling relief features in a die set to more accurately reproduce the intended flow channel features in the pressed plate. The process includes determining a target relief profile of features extending across the plate along at least a first dimension of the plate, modulating the relief profile with an over-profiling parameter, as a function of the first dimension; forming a die with the modulated relief profile; and pressing a flow field plate using the die with modulated relief profile to thereby produce the unmodulated, target relief profile in the flow field plate. |
