SYSTEM AND METHOD FOR DETECTING A FUEL TANK VALVE STATE IN A FUEL CELL ELECTRIC VEHICLE

A control system for a fuel cell electric vehicle (FCEV) includes a controller that is configured to control a fuel delivery system to release fuel via an injector with a selected fuel tank valve among a plurality of fuel tank valves controlled to be in an open state and with the other fuel tank valves controlled to be in a closed state. The control is further configured to cause a corrective action in response to a fuel characteristic indicating the selected fuel tank valve is stuck closed.
