Abstract
A fuel cell assembly is disclosed, the fuel cell assembly including a pair of terminal plates, one terminal plate disposed at each end of the fuel cell assembly, a fuel cell disposed between a pair of end fuel cells and the terminal plates, and a thermally insulating, electrically conductive layer formed between the fuel cell and one of the terminal plates adapted to mitigate thermal losses from the end plate, and fluid condensation and ice formation in an end fuel cell. The end fuel cells of the fuel cell assembly have a membrane and/or a cathode having a thickness greater than an average thickness of a membrane and/or a cathode disposed in the fuel cell that may be used in conjunction with, or instead of, the insulating layer to further mitigate thermal losses from the end plate, and fluid condensation and ice formation in the end fuel cells.
