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.

Pressure relief control system for a fuel cell system having a pressurized fuel flow

A technique includes providing fuel and oxidant flows to a fuel cell. The technique includes humidifying the anode of the fuel cell, including saturating the oxidant flow and maintaining a temperature of the oxidant flow above a temperature of the fuel cell such that excess water propagates from a cathode of the fuel cell to the anode.
