Abstract

An illustrative example fuel cell assembly includes a plurality of cells respectively including at least an electrolyte layer, an anode flow plate on one side of the electrolyte layer, and a cathode flow plate on an opposite side of the electrolyte layer. At least one cooler is situated adjacent a first one of the cells. The cooler is closer to that first one of the cells than it is to a second one of the cells. The cathode flow plates respectively include a plurality of flow channels and the anode flow plates respectively include a plurality of flow channels. The anode flow plates respectively include some of the flow channels in a condensation zone of the fuel cell assembly. The flow channels of the anode flow plate in the condensation zone of the first one of the cells have a first flow capacity. The flow channels of the anode flow plate of the second one of the cells that are in the condensation zone have a second flow capacity. The second flow capacity is greater than the first flow capacity.
