摘要:
Disclosed is a magnetic catalyst formed by a single or multiple nano metal shells wrapping a carrier, wherein at least one of the metal shells is iron, cobalt, or nickel. The magnetic catalyst with high catalyst efficiency can be applied in a hydrogen supply device, and the device can be connected to a fuel cell. Because the magnetic catalyst can be recycled by a magnet after generating hydrogen, the practicability of the noble metals such as Ru with high catalyst efficiency is dramatically enhanced.

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.

Solid-state hydrogen fuel with a polymer matrix and fabrication methods thereof are presented. The solid-state hydrogen fuel includes a polymer matrix, and a crushed mixture of a solid chemical hydride and a solid-state catalyst uniformly dispersed in the polymer matrix. The fabrication method for the solid-state hydrogen fuel includes crushing and mixing a solid chemical hydride and a solid-state catalyst in a crushing/mixing machine, and adding the polymer matrix into the mixture of the solid chemical hydride and the solid-state catalyst to process a flexible solid-state hydrogen fuel. Moreover, various geometric and/or other shapes may be formed and placed into suitable vessels to react with a particular liquid and provide a steady rate of hydrogen release.

A power supply device is provided. The power supply device includes a fuel cell, a hydrogen generator, a check valve and an exhaust valve. The fuel cell has a hydrogen inlet and a hydrogen outlet. The hydrogen generator is connected to the hydrogen inlet and used for generating hydrogen. The check valve is disposed in the hydrogen inlet and used for preventing the hydrogen within the fuel cell from flowing to the hydrogen generator, and preventing exterior air from entering the fuel cell. The exhaust valve is disposed in the hydrogen outlet for exhausting the hydrogen within the fuel cell.

A hydrogen generation system comprising solid hydrogen fuel, a liquid absorbent material, and a phase-change material is provided. When the liquid (usually water, alcohol, or aqueous solution of alcohol, aqueous solution of salt or aqueous solution of acid) in the absorbent material contacts with the solid hydrogen fuel, the solid hydrogen fuel will react with the liquid to release hydrogen and generate heat. The heat as generated will accumulate to increase the reaction temperature, and then boost the hydrogen-releasing rate. The phase-change material is adjacent to the solid hydrogen fuel for absorbing and storing the reaction heat, so as to stabilize the reaction temperature. Therefore, the hydrogen-releasing rate is kept as constant to achieve a steady hydrogen flow.
