Abstract: A device and method for improving cathode catalytic heating by allowing independently for a draining of a liquid and a purging of a gas in a fuel cell at cold starts via a system including an anode drain and a cathode catalytic heating system connected by a purge tube, a sump external to the purge tube, and a pintle having a closed position, a first open position, and a second open position.

Abstract: A fuel cell system is provided which includes a compression retention enclosure with upper and lower compression shells and side sheet components coupled by interlocking hem joints. Methods for manufacturing compression retention enclosures with hem joints such that the enclosure remains sealed upon operational swelling of the fuel stack are also provided. A compression shell may be formed from a light weight composite structure having a polymeric layer interposed between steel skins, and an extension of the top steel skin may form a hemmed edge or may form a side sheet having a hemmed edge. Side sheet panels may be coupled to the end plates by interlocking two opposing hemmed edges to form the hem joint, or by sliding an opposing C-linking element between two hemmed edges held under compression force in an interlocking position.
