A fuel cell system including a fuel cell stack that employs a thermal sub-system having a specialized radiator. The cooling fluid from the fuel cell stack is directed through the radiator to remove or dissipate waste heat before the cooling fluid is returned to the stack. The radiator includes a selectively permeable wall that allows liquid water or water vapor to selectively permeate therethrough to the outside of the radiator, where it is evaporated to increase the cooling ability of the radiator. A water separator separates water from the cathode exhaust of the fuel cell stack, which is used to replenish water in the cooling fluid that is evaporated through the radiator wall.
