    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.

    摘要： A fluidized contaminant separator and water-control loop (10) decontaminates a fuel reactant stream of a fuel cell (12). Water passes over surfaces of an ammonia dissolving media (61) within a fluidized bed (62) while the fuel reactant stream simultaneously passes over the surfaces to dissolve contaminants from the fuel reactant stream into a separated contaminant and water stream. A fuel-control heat exchanger (57) upstream from the scrubber (58) removes heat from the fuel stream. A water-control loop (78) directs flow of the separated contaminants and water stream from an accumulator (68) through an ion exchange bed (88) which removes contaminants from the stream. Decontaminated water is directed back into the scrubber (58) to flow through the fluidized bed (62). Separating contaminants from the fuel reactant stream and then isolating and concentrating the separated contaminants within the ion exchange material (88) minimizes costs and maintenance requirements.

    摘要： An example fuel cell arrangement includes a fuel cell stack configured to receive a supply fluid and to provide an exhaust fluid that has more thermal energy than the supply fluid. The arrangement also includes an ejector and a heat exchanger. The ejector is configured to direct at least some of the exhaust fluid into the supply fluid. The heat exchanger is configured to increase thermal energy in the supply fluid using at least some of the exhaust fluid that was not directed into the supply fluid.
