Abstract

The invention relates to a metal hydride hydrogen compression device with a heat source and a manufacture method thereof. The manufacture method is characterized in that the metal hydride hydrogen compression device is heated by self under the condition of no additional heat sources, and then the metal hydride hydrogen compression device adsorbs hydrogen at the room temperature and discharges high-voltage hydrogen at high temperature. The device comprises a hydrogen compression part with metal hydride and a heat source part, wherein a phase change energy storage material in the heat source part is subjected to temperature raising and phase change and stores heat under the heating condition, and heat is provided for the metal hydride in the hydrogen compression part; then, the metal hydride releases hydrogen at a certain temperature range of 50-300DEG C in more than two hours; and the hydrogen release pressure is between 10MPa and 100MPa.

Description

technical field [0001] The invention relates to the field of hydrogen preparation, purification and compression, in particular to a metal hydride hydrogen compression device that absorbs hydrogen at room temperature and uses its own heat source to heat and release high-pressure hydrogen and a manufacturing method thereof. Both the heat source part and the metal hydride hydrogen compression part are made of stainless steel, and the phase change energy storage material and the metal hydride material are sealed into the heat source part and the hydrogen compression part respectively. Under the working condition of no external heat source, the heat source part The phase-change energy storage material in the metal hydride provides heat for the hydrogen compression part of the metal hydride, so that it releases high-pressure hydrogen at high temperature to achieve the purpose of pressurizing hydrogen. Background technique [0002] The metal hydride hydrogen compression device util...
