Low-pressure hydrogen produced in water electrolysis is pressurized and then can be directly stored for use, thus achieving the effect of reducing the cost and improving the safe reliability and the like.

Description

technical field [0001] The invention relates to a fuel cell and a high-pressure hydrogen generating device, in particular to a proton exchange membrane hydrogen electrochemical supercharging device. Background technique [0002] Hydrogen is the power source of regenerative fuel cells, stationary hydrogen refueling stations, and transportation vehicles using fuel cells. In order to meet their needs, high-pressure hydrogen that can be directly stored in gas cylinders must be produced. At present, if the hydrogen produced by atmospheric pressure water electrolysis technology is to be stored, a gas compression pump must be provided to make it reach the set high pressure value before it can be stored in the gas cylinder, which leads to the overall equipment of the water electrolysis system Heavy, high energy consumption, reduced reliability, and reduced electrolysis efficiency.

Problems solved by technology

At present, if the hydrogen produced by atmospheric pressure water electrolysis technology is to be stored, a gas compression pump must be provided to make it reach the set high pressure value before it can be stored in the gas cylinder, which leads to the overall equipment of the water electrolysis system Heavy, high energy consumption, reduced reliability, and reduced electrolysis efficiency

[0003] However, water electrolyzers that use high-pressure water pumps to supply water with high pressure or partial high-pressure operation have defects such as complex structure, high cost, and potential safety hazards.
