Abstract
A fuel cell system has a fuel cell () performing power generation as a result of reactions in supplied gases, a humidifying device () for humidifying at least one supplied gas by using water from water tank (), and a coolant temperature regulation device () for regulating the temperature of the coolant flowing within the fuel cell () in order to control the temperature of the fuel cell (), and a defrosting device (). The defrosting device () melts ice in the water tank () during a startup operation of the fuel cell system by applying heat contained in the coolant to the ice. Here, the coolant has an increased temperature as a result of waste heat produced during power generation inside the fuel cell ().
