Embodiment Construction

[0020] refer to image 3 As shown, the hydrogen storage alloy reactor 50 of the present invention is mainly composed of a container 51 and a plurality of sintered compacts 53. The sintered compacts 53 are formed by sintering hydrogen storage alloy powder and installed in the container 51. In order to facilitate installation in the container 51, the sintered molded body 53 should be made into a uniform specification, and a heat conduction sheet 54 is arranged between each sintered molded body 53 to improve the thermal conductivity of the reactor. The center of the sintered molded body 53 and the heat conducting sheet 54 is provided with a communicating hole to form a hydrogen channel for the reactor. If a plurality of communication holes are formed at corresponding positions of the sintered compact 53 and the heat conducting sheet 54, a plurality of hydrogen gas passages can be formed in the reactor. The communication holes on the sintered molded body 53 and the heat conductin...

Abstract

A hydrogen accumulating alloy reactor is composed of a container, multiple sintered bodies made of hydrogen accumulating alloy powder and with central through holes to form a hydrogen channel after their are installed in said container, the heat conducting pieces between adjacent sintered bodies, and net filters arranged in said central through holes. Its advantages are assembling efficiency and high thermal efficiency.

Description

1. Technical field: [0001] The invention relates to a hydrogen storage alloy reactor, in particular to a hydrogen storage alloy reactor formed by sintering hydrogen storage alloy powder. 2. Background technology: [0002] Generally, hydrogen is stored in a high-pressure vessel under high pressure or cooled to a very low temperature to store it in a liquid state. However, due to the very low density of hydrogen, the amount of hydrogen that can be stored in a high-pressure container is very small, so that the container for storing hydrogen is bulky and heavy, causing many inconveniences in transportation and use. Recently, hydrogen storage alloys have been used to solve the problem of hydrogen storage, that is, hydrogen storage alloys are used to absorb hydrogen for storage. From the perspective of weight ratio, the capacity of hydrogen storage alloy to store hydrogen is still relatively low, but in terms of volume ratio, it is higher than that of compressed hydrogen and liqu...
