Abstract

The invention provides a proton exchange membrane water electrolysis device which is a small hydrogen/oxygen generating device. The proton exchange membrane water electrolysis device comprises two anode plates, a negative bipolar plate and a membrane electrode between two anode plates and the negative bipolar plate; moreover, an anode end plate and an insulation spacer are sequentially arranged at two ends of the anode plate, sealing gaskets are respectively arranged between the anode plate and the membrane electrode and between the membrane electrode and the negative bipolar plate, and screw rods and nuts are used for fastening into the sealing gaskets, the anode plate, the membrane electrode and the negative bipolar plate into one body. The adopted working medium is pure water, the proton exchange membrane water electrolysis device has the characteristics of mild working conditions and high electrolytic efficiency, the purity of the produced gas is high, the operation is simple, and the proton exchange membrane water electrolysis device can be combined with a solar cell and a fuel cell to form a high-efficiency renewable energy utilization system.

Description

[0001] technical field [0002] The invention relates to a proton exchange membrane water electrolysis device, in particular to the structural design and flow field design of the proton exchange membrane water electrolysis device. Background technique [0003] As a clean, efficient energy source and energy carrier with unlimited raw materials, hydrogen energy can be used in conjunction with solar power generation and hydrogen-oxygen fuel cells, and is a key link in the clean and efficient use of renewable energy. Among them, PEM pure water electrolysis technology is currently the key development and even the preferred method in the field of hydrogen production. [0004] High-purity hydrogen and oxygen can be obtained by using a proton exchange membrane water electrolysis device. The principle is that there are electrode catalytic layers on both sides of the proton exchange membrane to obtain an electrolyte membrane-electrode structure, and its two sides are in close contact ...
