Abstract:
A fuel cell system includes at least one fuel cell stack designed to react reactants for current generation, a cold start detection apparatus for detecting a cold start state of a fuel cell stack and a load which may be connected to the fuel cell stack 2. A control device is designed to connect the load when the fuel cell stack 2 is in the cold start state. The supply of the reactants for the fuel cell stack is conformed to connection of the load, and the control device is designed with software and/or circuitry so as to vary the connected load in one or more step load changes in response to detection of the cold start state of the fuel cell stack.
