HYBRID COOLING SYSTEM FOR FUEL CELL

A hybrid cooling system for a fuel cell vehicle utilizes evaporative cooling to supplement a radiator. Liquid water produced by the fuel cell is utilized by the evaporative cooling system. A vacuum pump lowers a pressure in a chiller to increase the rate of evaporation of the liquid water. A control system manages capture of liquid water during periods of low fuel cell power demand for use during periods of high fuel cell power demand.
