Method to minimize the impact of shunt currents through aqueous based coolants on PEM fuel cell bipolar plates

Method to minimize the impact of shunt currents through aqueous based coolants on PEM fuel cell bipolar plates

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 f...

description 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.
