A device has an annulus having a first end and a second end. A valve plate is coupled to the first end of the annulus by a fastener, wherein the valve plate is adapted to contact a valve seat on a hydrogen producing fuel cover. A diaphragm is coupled to the second end of the annulus by a fastener, wherein the annulus extends through a container for holding the hydrogen producing fuel and wherein the diaphragm moves the valve plate relative to the valve seat responsive to a different in pressure across the diaphragm.
