Abstract
The invention relates to a fuel cell system. The system has one operational state in which a fuel gas supply is connected to the anode flow field plates along a flow path. The system also has a different operational state in which the anode flow field plates are disconnected from the fuel gas supply and connected to an oxidant gas supply along a flow path. The fuel cell system can use a valve and a control system to switch the operational state of the system.
