Abstract: A cooling subsystem of a fuel cell assembly that employs the Rankine cycle to use the potential energy of a thermally pressurized fluid to generate electrical power. Waste heat from a fuel cell stack is transferred to working fluid in a heat exchanger. The working fluid in the condensed phase is pressurized, evaporated in a boiler or evaporator, and then fed to an expansion turbine which in turn provides rotary motion to an electric generator to generate useful electrical power. The fluid leaves the turbine as a lower pressured vapor, and is then condensed back to a fluid and pumped back to the evaporator to repeat the process.

Abstract: A fuel cell system bipolar plate formed of a graphite metal composite. The bipolar plate is formed of a metal foil formed of tantalum or a metal having a tantalum coating. Flexible graphite deposited in rows on each surface of the metal foil forms channels of the bipolar plate and providing a flow field. The graphite metal composite provides flexural strength as well as resistance to corrosion.
