A release valve is disclosed which in one embodiment includes a housing having a passageway extending therethrough and defining an inlet and an outlet, and a membrane extending across the passageway between the inlet and the outlet. The membrane is operable to permit passage through the passageway of gas at a first pressure, inhibit passage through the passageway of liquid at the first pressure, and permit passage of liquid at a second pressure greater than the first pressure. The release valve may also include a check valve for inhibiting passage of gas from the outlet to the inlet. The release valve is suitably employed in fuel cell systems such as in a cooling system thereof.

Release valve and method for venting a system

An assembly includes a fuel cell stack, a circuit board, an elastomeric connector and a frame. The elastomeric connector contacts the stack to provide cell voltages of the stack to the circuit board. The frame holds the circuit board, positions the elastomeric connector between the fuel cell stack and the circuit board and provides the appropriate compression of the connector.
