Abstract:
A fuel cell includes a first valve metal flow field plate. The first valve metal flow field plate has a first cooling channel adapted to receive an aqueous coolant and to contact the aqueous coolant at a position that inhibits the formation of shunt currents when the fuel cell is incorporated in a fuel cell stack. A field assembly includes a first metal flow field plate having a first cooling channel adapted to receive an aqueous coolant is also provided. A valve metal plate is disposed over the first metal flow field plate in the flow field assembly. Fuel cell stacks using the valve metal-containing flow field plates are also provided.
