Description
Summary:Previous research shows that the power density of polymer electrolyte fuel cell can be increased by applying porous metal as a flow fields, supplying reactants evenly to the whole electrode areas as compared to the operation with conventional groove type flow fields. This paper investigates the effect of introducing none-woven metal fabric as flow fields. The investigations here revealed that the metal fabric shows higher maximum power output than groove due to a reaction resistance reduction. The effects above was observed in various flow feeds. The reduction of the resistance was significant in cathode, due to better water transport.
