摘要： A fuel cell system includes a fuel cell stack having an anode plate and a cathode plate arranged on opposing sides of a proton exchange membrane. Cooling channels are in thermal contact with at least one of the anode plate and the cathode plate and include an internal coolant passage. A pressure-drop device is provided in the coolant channels and is configured to provide a sub-atmospheric pressure within the coolant passage. In one example, the coolant within the coolant passage is at less than ambient pressure. A compression device fluidly interconnects to and is downstream from the internal coolant passage by a coolant system loop and configured to convey a sub-atmospheric pressure coolant steam. The compression device is configured to increase the pressure and a temperature of the sub-atmospheric coolant steam to a super-atmospheric pressure and maintain the coolant steam within a steam region of a pressure-enthalpy curve.

摘要： A thermal priority fuel cell power plant includes a cell stack assembly for generating an electrical power output. The cell stack assembly includes an anode, a cathode, and a waste heat recovery loop. The anode is configured to receive a fuel, the cathode is configured to receive an oxidizer, and the cell stack assembly is configured to generate the electrical power output by electrochemically reacting the anode fuel and the cathode oxidizer in the presence of a catalyst. The waste heat recovery loop includes a coolant inlet conduit and a coolant outlet conduit, and is configured to remove waste heat generated from the electrochemical reaction. A waste heat recovery loop is thermally coupled to the cell stack assembly for managing the waste heat of the cell stack assembly and for supplying thermal power to a thermal load demand. The waste heat recovery loop includes a heat exchanger in heat exchange relationship with the coolant outlet conduit and the thermal load demand. A controller is operatively associated with the cell stack assembly and the waste heat recovery loop. The controller controls the operation of the cell stack assembly by adjusting a fuel cell power plant parameter responsive to the thermal load demand. In one aspect, the fuel cell power plant parameter is reactant utilization. In another aspect, the fuel cell power plant parameter is a temperature for a thermal management system accumulator.
