  • Device and method to release the overpressure of a fuel cell coolant tank
    Patent number: 7413822
    Abstract: A device and method to convert residual hydrogen present in a fuel cell cooling system into water. An oxygen-bearing fluid is supplied to the cooling system from a source that also has elevated moisture levels to minimize the likelihood that the oxygen-bearing fluid will dry out or otherwise deplete the coolant in the cooling system. One or more valves are included to avoid the formation of adverse pressure gradients that could inhibit the continued supply of the oxygen-bearing fluid to the cooling system.
    Type: Grant
