Zusammenfassung:	An apparatus for heating a fuel cell stack in a cold start mode is provided. The apparatus comprises a fuel cell stack, a power converter, and a controller. The power converter may include a power switch and resistive heating element that is thermally coupled to the fuel cell stack. The controller is configured to activate the power converter, if a temperature is below a predetermined temperature value, to draw current from the fuel cell stack to cause the fuel cell stack to generate heat. Heat from the power converter is also applied to the fuel cell stack.
