FUEL CELL SEALING CONFIGURATION

摘要

A fuel cell plate includes a structure having opposing sides bounded by a periphery providing at least one edge. Gas flow channels are arranged on the one side and arranged within a perimeter that is spaced inboard from the periphery to provide a first gasket surface between the perimeter and the periphery. Inlet and outlet flow channels are arranged on the other side and extend to the periphery and are configured to provide gas at the at least one edge. Holes extend through the structure and fluidly interconnect the inlet and outlet flow channels to the gas flow channels. In one example, the fuel cell plate is a water transport plate in a fuel cell having external manifolds that supply fluid to the plate.
