Description

Technical Field

Background
In recent years, with the increase of greenhouse gas emission, global climate is continuously warmed, and the climate problem is increasingly highlighted. In order to solve the challenge, main countries around the world sign Paris climate agreement in 2016, form climate consensus and make carbon dioxide emission reduction plans. To achieve this goal, it is becoming more and more urgent to replace the current high carbon fossil energy sources such as coal, petroleum and the like with low carbon clean renewable energy sources. In this energy revolution, hydrogen energy is the first choice of technology for competitive development of new energy in various countries because of its advantages of cleanness, no pollution, high energy density per unit mass, storability, renewability, wide source, etc., and is even called as the "ultimate energy" in the 21 st century.
At present, hydrogen production mainly comes from natural gas hydrogen production or coal hydrogen production, carbon dioxide is generated in the production process, and the production belongs to 'grey hydrogen', and the development direction accepted in the industry at present is 'green hydrogen', namely, no carbon dioxide is generated in the hydrogen production process. The current primary mode of production of green hydrogen is electrolysis of water, which is energized by electrical energy to break down water molecules into hydrogen and oxygen gases at the electrodes.
The main production plants for the electrolysis of water are electrolysis cells, which can be classified into 3 groups, i.e. alkaline electrolysis cells (AWE), proton exchange membrane electrolysis cells (PEM), Solid Oxide Electrolysis Cells (SOEC), according to the electrolyte. SOEC cells are still in the laboratory stage and are not commercially available. The AWE electrolytic tank consists of electrodes, electrolyte and diaphragm, the electrolytic tank is filled with electrolyte solution, the tank body is divided into a cathode chamber and an anode chamber by the diaphragm, and each electrode is arranged in the chamber. The proton exchange membrane electrolyzer (PEM) is the most mature technology developed at present, has the advantages of simple structure, safety, reliability, long service life, simple and convenient operation, low price, and the like, but has the defects of low efficiency, need of using strong corrosive alkali liquor, water and alkali removal of hydrogen, difficulty in quick start and load change, incapability of quickly adjusting the hydrogen production speed, and the like, so the PEM has poor adaptability to power generation by renewable energy sources, and is difficult to overcome due to the technical characteristics of alkaline electrolyzers, so that the PEM is increasingly emphasized by people in recent years. The PEM electrolytic cell has the advantages of compact structure, high efficiency, low energy consumption, fast response, high load and the like, and is the main flow direction of electrolytic hydrogen production in the future. The PEM electrolyzer adopts a high molecular polymer proton exchange membrane to replace a diaphragm and liquid electrolyte in the alkaline electrolyzer, and has double functions of ion conduction and gas isolation. The PEM electrolyzer consists of membrane electrode, bipolar plate and other parts, and the membrane electrode consists of proton exchange membrane and anode and cathode catalyst.
The development of PEM electrolyzers mainly solves the preparation technology of membrane electrodes, and in the preparation of membrane electrodes, the selection of catalysts and the composition of catalyst slurry are always the key points of research.
