Abstract

The invention discloses a device for controlling hydrogen release efficiency of alloy hydrogen storage equipment. The device comprises a fuel cell, a semiconductor chilling plate, the alloy hydrogen storage equipment and a heat-conducting medium, the alloy hydrogen storage device is connected with the fuel cell through a pipeline, and the cold end and the hot end of the semiconductor chilling plate are connected with the fuel cell and the alloy hydrogen storage device through heat conduction media respectively. The invention has the beneficial effects that when the fuel cell works, the hot endof the semiconductor chilling plate heats and preserves heat of the alloy hydrogen storage equipment through the heat-conducting medium, and the cold end dissipates heat and cools the fuel cell through the heat-conducting medium, so that the alloy hydrogen storage equipment and the fuel cell are kept in a proper temperature interval to achieve the optimal working efficiency; when the alloy hydrogen storage device is filled with hydrogen, the semiconductor chilling plate exchanges the cold end and the hot end by changing the current direction, the cold end cools the alloy hydrogen storage device through the heat conduction medium to improve the hydrogen filling rate, and the hot end takes cooling measures to reduce the temperature of the alloy hydrogen storage device.

Description

technical field [0001] The invention relates to a hydrogen fuel cell system and the application field of alloy hydrogen storage technology, in particular to a device for controlling the hydrogen release efficiency of alloy hydrogen storage equipment. Background technique [0002] As the research and application of hydrogen fuel cells are paid more and more attention, the storage and transportation of hydrogen has also become the focus of attention. Among them, alloy hydrogen storage is an extremely convenient and ideal hydrogen storage method. The use of hydrogen storage alloys for hydrogen storage not only has the characteristics of large hydrogen storage capacity, low energy consumption, low working pressure, and convenient use, but also eliminates the need for Bulky steel container for easy and safe storage and transport. [0003] Since the hydrogen storage alloy has the characteristics of releasing a large amount of heat during the hydrogen absorption chemical reaction ...
