摘要： 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.

摘要： 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.

摘要： A fuel cell-based system including equipment not classified to operate in a flammable environment, a detector to detect a flammable gas, and a component capable of leaking a flammable gas are arranged in an enclosure. The component is positioned above the unclassified equipment and below the sensor, and a buoyancy path is provided such that the unclassified equipment is isolated from flammable gas emitted by the component in the enclosure while a ventilation system is not energized. In addition, the detector is placed in the buoyancy path so that when the system is started from a de-energized state, the detector can determine whether an unacceptable concentration of flammable gas is present in the enclosure. When the system is energized, the ventilation system creates an air stream through the enclosure. The ventilation system is arranged such that unclassified equipment is upstream of flammable gas that is emitted by the component in the enclosure.
