Abstract: Disclosed is super water absorbent polymers applied to contain water, and the polymers may further collocate with water absorbent cotton materials to accelerate water absorbent rates. The described water absorbent materials are combined with solid hydrogen fuel to complete a stable hydrogen supply device. Performance of the hydrogen supply device is not effected by inverting or tilting thereof. Even if inverting or tilting the device, the water contained in the water absorbent materials does not flow out from the device. As such, the MEA film in the fuel cell connected to the hydrogen supply device will not blocked by the water, thereby avoiding the fuel cell performance degradation even breakdown.

Abstract: A solid hydrogen fuel is formed into a solid pressure-formed block. The method of manufacturing the solid hydrogen fuel includes following steps. First, at least a hydride powder and at least a hydrogen releasing catalyst powder are mixed well. Next, the mixed powder is bonded into a block by pressure. When in use, the solid hydrogen fuel is mixed with water to produce hydrogen. The hydride powder and water bring about a hydrogen releasing reaction. The hydride releasing catalyst powder is used for catalyzing the hydrogen releasing reaction to produce hydrogen. The solid hydride has higher hydrogen production and can release hydrogen completely.
