Fuel cell stack with heat exchanger

A fuel cell (10, 10', 10") includes a fuel cell stack (12, 12', 12", 40, 40', 42) and a heat exchanger (14, 14', 24, 24') in fluid and thermal communication with the fuel cell stack (12, 12', 12", 40, 40', 42). The heat exchanger (14, 14', 24, 24') is adjacent the fuel cell stack (12, 12', 12", 40, 40', 42) and both removes excess heat from the fuel cell stack (12, 12', 12", 40, 40', 42) and preheats a gas before entry into the fuel cell stack (12, 12', 12", 40, 40', 42).
