A cooling system is connected to a fuel cell stack (10) which has a hydrogen inlet (12), an air inlet (14), a coolant inlet (16), a coolant outlet (18) and an exhaust water outlet (20). The cooling system includes a heat exchange unit (22, 76) coupled to the coolant inlet (16) and the coolant outlet (18), a coolant pump (96) for circulating coolant therethrough, and a blower (37, 66) for blowing air through the heat exchange unit (22, 76). The cooling system also includes an evaporator unit (54, 74) exposed to the blown air, and a conduit (40, 44, 75) which communicates exhaust water from the fuel cell stack exhaust water outlet (20) to the evaporator unit (54, 74). The exhaust water evaporates in the blown air and thereby cools the air and reduces the amount of liquid exhaust water. |
