  • EXPLOSION-PROTECTED FUEL CELL
    Publication number: 20130209910
    Abstract: A fuel cell arrangement operable in environments that are prone to explosions including a fuel cell stack 14 that is housed in a containment vessel 15 filled with a heat equalizing fluid 26 and provided with a cooling system. The heat equalizing fluid 26 flows around all sides of the fuel cell stack 14 and prevents a direct concentrated heat transfer from the surface of the fuel cell stack 14 to the containment housing 15. The heat equalizing fluid 26 buffers and distributes local heat peaks originating from the fuel cell stack 14 and thus eliminates ignition sources.
