A PEM fuel cell having serpentine flow field channels wherein each channel has an inlet leg, an exit leg, at least one medial leg therebetween and hairpin curves connecting the legs to each other. The legs all extend in the same general direction between a gas supply and gas exhaust manifold. One of the inlet and exit legs is longer than the other while the medial leg is shorter than the shortest of the inlet/exit leg. The land(s) defining the medial leg(s) of adjacent channels are generally aligned lengthwise. <IMAGE> |
