Abstract
A fuel cell-based system includes an electromechanical pressure relief system to prevent an overpressure condition from damaging the anode circuit of a fuel cell stack or creating a hazardous environment. Upon detection of a fuel flow pressure in a fuel path between a fuel source and the fuel cell stack, the pressure relief system isolates the anode circuit from the fuel path, vents the fuel flow, and shuts down the fuel cell system.
