Abstract

The invention discloses a high pressure proton membrane water electrolysis device. The device comprises a water tank, a make up pump, an electrolytic cell stack, a first separator and a second separator, wherein the make up pump is used for communicating the water tank with a water inlet of the electrolytic cell stack; the first separator is communicated with an oxygen outlet of the electrolytic cell stack; the second separator is communicated with a hydrogen outlet of the electrolytic cell stack; and an electrolyte and proton exchange membrane is arranged in the electrolytic cell stack and is solid polymer electrolyte. The high pressure proton membrane water electrolysis device has the beneficial effects that the device avoids that the gases generated in traditional methods for electrolyzing water contain alkaline aerosol; and water and gas separation is carried out on the generated gases by the first and second separators, thus greatly improving the purity of the gases generated by electrolyzing water. The invention also discloses a high pressure proton membrane water electrolysis method.

Description

technical field [0001] The invention relates to the technical field of electrolysis, in particular to a high-voltage proton membrane water electrolysis device and method. Background technique [0002] Similar to traditional gasoline vehicles, fuel cell electric vehicles store energy through external fuel. In hydrogen-oxygen fuel cells, hydrogen is its fuel, and the hydrogen produced by proton membrane water electrolysis is one of the most suitable hydrogen sources for fuel cells due to its high purity. In the application of renewable energy such as wind energy and solar energy, there are instability of wind energy and solar energy or the inconvenience of energy output. One of the best solutions is to use the remaining energy for water electrolysis to produce hydrogen, and then store The hydrogen is then used for power generation or transported to the place of use through pipelines. In these processes, high-pressure water electrolysis is required to produce hydrogen. [00...
