Abstract
A fuel cell system has a compressor delivering compressed gas to a fuel cell stack and a control valve affecting the flow of compressed gas. A load dump condition is determined for the fuel cell stack. The flow through the compressor is increased and the additional flow diverted away from the fuel cell stack by the control valve to provide additional load for the fuel cell stack. The fuel cell stack may then be operated at a higher output power for the purpose of generating more waste heat to more rapidly warm itself.
