Proton exchange membrane water electrolysis cell

Abstract

The invention relates to a proton exchange membrane water electrolysis cell which comprises a proton exchange membrane, a cathode catalyst layer, an anode catalyst layer, a cathode diffusion layer andan anode diffusion layer. The cathode catalyst layer and the anode catalyst layer are respectively formed, in a spray coating manner, on two sides of the proton exchange membrane to form a membrane electrode with a three-in-one structure; the membrane electrode is mounted in the middle of the middle substrate; a cathode flow field plate and an anode flow field plate are arranged on the two sidesof the middle substrate respectively; a left epoxy resin plate is arranged at the left end of the cathode flow field plate; a right epoxy resin plate is arranged at the right end of the anode flow field plate; current collecting plates are embedded in the middle parts of the left epoxy resin plate and the right epoxy resin plate; and the left end plate, the left epoxy resin plate, the cathode flowfield plate, the middle substrate, the anode field flow plate, the right epoxy resin plate and the right end plate are provided with communicated gas-liquid pore channels. The essential exchange membrane water electrolysis cell can improve the electrolysis efficiency, reduce the current loss, reduce the mass and size of the water electrolysis cell, reduce the assembly difficulty and prolong the service life.

Description

technical field [0001] The invention relates to the field of proton exchange membrane electrolyzed water, in particular to a proton exchange membrane water electrolyzer. Background technique [0002] Hydrogen energy is regarded as the most ideal energy carrier due to its clean, pollution-free, efficient, storable and transportable advantages. Hydrogen production by electrolysis of water is currently the easiest way to obtain pure hydrogen. If it is combined with renewable resource power generation technology, electrolysis of water can be used as a large-scale hydrogen production technology, which has less environmental pollution, less greenhouse gas emissions, and is more economical. Well, it has a good application prospect. [0003] Proton exchange membrane electrolysis water technology is to generate oxygen and hydrogen through electrolysis of water. Deionized water flows into the channel through the deionized water, diffuses to the anode side of the proton exchange membr...
