Abstract
Removal of waste heat from a fuel cell is necessary for continuous operation. Evaporation, can be used to remove the heat produced by the exothermic reaction within the fuel cell. Water sprayed into a gaseous fuel stream is evaporated in an evaporative cooler adjacent to the fuel cell. The fuel/steam stream can then be utilized in the various other fuel cell system operations.
