Abstract:
1. A fuel cell comprising: a cathode layer; an anode layer; and a single heat exchange plate in heat exchange relationship with one of said anode layer and cathode layer and having a series of cooling channels and a series of heating channels formed therein, wherein each of said series of cooling channels are in fluid connection with a coolant header and each of said series of heating channels are in connection with a mixture header, wherein said heating channels and said cooling channels have separate and isolated contents therein, said heating channels including a catalyst coating that promotes an exothermic hydrogen oxidation reaction, wherein said cooling channels are adjacent to said heating channels, all cooling channels and heating channels lie within a single plane of said heat exchange plate, all cooling channels and heating channels have the same directional orientation, and said heat exchange plate modulates temperature of the fuel cell during park, start-up, and normal operation.
