Hydrogen has wide application in industrial fields such as chemical synthesis; and as an energy carrier, it has great advantages in energy production and various end uses, contributing to decarbonization of the most energy intensive sectors in our economy. Currently, most hydrogen is produced by fossil fuels, which results in massive consumption of fossil fuels and emission of greenhouse gases, causing global warming. In addition, additional purification steps are required to meet the requirements of a particular application.
The electrolytic hydrogen production has the advantages of small pollution, high hydrogen purity, zero carbon emission and the like, and can convert renewable energy sources such as wind energy, solar energy and the like into available chemical substance energy through water electrolysis hydrogen production. The method is to construct a zero-carbon-emission hydrogen-electricity circulation system, store intermittent surplus renewable power and solve the problem of unstable renewable energy sources. However, the hydrogen evolution reaction and the oxygen evolution reaction in the traditional hydrogen production mode are in the same space, and the middle is separated by an ionic membrane. At low current densities, this approach may risk hydrogen and oxygen crossing over, the system is highly pressurized and the anode and cathode pressures must be carefully controlled to prevent gas permeation through the separator. The explosion limit of hydrogen is very broad and there is an explosion risk in the collection. In addition, in the large-scale popularization and application, hydrogen and oxygen are required to be collected from each small unit, so that the hydrogen production cost is further increased, and the risk of hydrogen and oxygen in a mutually-stringing manner is increased.
