Abstract: A hydrogen circulation system for fuel cell includes a hydrogen supply pipeline, a return pipeline, a buffer tank, an ejector, a differential pressure valve, a solenoid valve, and a controller. The return pipeline connects a hydrogen outlet of a fuel cell stack and the hydrogen supply pipeline. The buffer tank is installed at the return pipeline. The ejector is installed at the hydrogen supply pipeline for connecting the buffer tank. The differential pressure valve is between a hydrogen source and the ejector for adjusting a pressure in the hydrogen supply pipeline based on a pressure difference between an anode inlet and a cathode inlet of the fuel cell stack. The solenoid valve is installed at the return pipeline between the buffer tank and the hydrogen outlet. According to an output voltage or a load of the fuel cell stack, a switch of the solenoid valve is controlled by the controller.

Abstract: 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.

Abstract: 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.

Abstract: 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.

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.
