Design cleverly cools the system and promotes air flow.
Two independent cooling systems are used—a FC cooling system that uses cooling fluid just for the FC to cool the FC stack, and an EV cooling system that cools the inverter and motor system.
The FC cooling system uses a pump to circulate cooling fluid between a radiator and the fuel cell, similar to the cooling system of a conventional engine automobile, to prevent the temperature of the FC stack from increasing too much from the heat produced when the fuel cell generates electricity. In order to prevent short circuits from the FC stack via the cooling fluid, an ion exchanger is also used to ensure that the cooling fluid is non-conducting.
