NOVELTY - Supercharger (62) in fluid communication with exhaust passage (38) selectively pressurizes process exhaust stream and sends it to pressurized condensing heat exchanger (66). The exchanger has pressure valve (10) at outlet (72) to restrict discharge of process exhaust stream to outside, to pressurize within exchanger. The exchanger directs condensed water to coolant loop (42) via condensed water line (80).    USE - For fuel cell power plant used to produce electrical energy from reducing and oxidizing fluids to power electrical apparatus such as electric vehicles for transportation, portable or stationary power plants.    ADVANTAGE - Adjusts pressure high enough for recovering appropriate amount of water to maintain the fuel cell power plant in water balance at a particular process exhaust stream temperature achieved by high temperature ambient air cooling fluid. Since the process exhaust is restricted to be discharged, and pressurized inside the heat exchanger to about 20 pounds per square inch, fuel cell power plant is prevented from moving out of water balance. Provides the recovery system that requires only temporary parasitic power demands to enhance water recovery during short-duration hot weather operations and thereby permits the plant to operate more efficiently under normal non-hot weather operations. Increases heat rejection capacity of condensing heat exchanger of plant during hot weather operation. Increases water recovery capacity of the plant without altering structural characteristics or operation of fuel cell and/or coolant loop components of plant.    DETAILED DESCRIPTION - A fuel cell (12) has electrolyte (14) between anode (16) and cathode (18) to produce electric current from reducing fluid and oxidant stream. The coolant loop sends coolant fluid from coolant receiver through the coolant passage (50) to fuel cell and back to reservoir for cooling the cell. The process exhaust passage directs the received cathode exhaust stream from cathode exhaust passage as process exhaust stream out of the fuel cell. An INDEPENDENT CLAIM is also included for method of operating pressurized water recovery system.
