Hydrogen bottle module with low-pressure alloy hydrogen storage bottle matched with medium-pressure hydrogen storage bottle

Abstract

The invention discloses a hydrogen cylinder module with a low-pressure alloy hydrogen storage cylinder matched with a medium-pressure hydrogen storage cylinder, and relates to the technical field of hydrogen storage, the hydrogen cylinder module comprises the low-pressure alloy hydrogen storage cylinder and the medium-pressure hydrogen storage cylinder, and further comprises a heat transfer pipeline arranged in the low-pressure alloy hydrogen storage cylinder, one end of the heat transfer pipeline penetrates out of the low-pressure alloy hydrogen storage bottle and is provided with a second control valve, the second control valve is connected with a flow controller, and a heat transfer medium enters the low-pressure alloy hydrogen storage bottle through the second control valve and the heat transfer pipeline; the fuel cell is connected with a gas inlet pipe, and a gas pipe led out of the low-pressure alloy hydrogen storage bottle is sequentially connected with a first control valve and a low-pressure hydrogen switching valve in series and is connected with the fuel cell through the gas inlet pipe; in the hydrogenation process of the hydrogen cylinder module, hydrogen of a hydrogen refueling station can be injected into a hydrogen cylinder without pressurization, and the hydrogenation process is simple and easy to operate; the problem that a low-pressure alloy hydrogen storage bottle cannot release enough hydrogen instantly is solved.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage, in particular to a hydrogen bottle module in which a low-pressure alloy hydrogen storage bottle is matched with a medium-pressure hydrogen storage bottle. Background technique [0002] A fuel cell vehicle is a high-efficiency, zero-emission clean vehicle that uses hydrogen as fuel and converts hydrogen into electricity through a fuel cell. When hydrogen needs to be used, it needs to be stored in gas storage cylinders. [0003] The invention patent with the application number CN113130940A discloses a fuel cell vehicle hydrogen storage system with mixed high and low pressure hydrogen cylinders. It uses hydrogen storage cylinders of different pressure specifications, has a high degree of freedom in design, and can flexibly choose a low pressure hydrogen storage scheme and Low hydrogenation cost hydrogenation and hydrogenation scheme; in the hydrogenation process, the empty low-pressure gas ...
