With the signing of greenhouse gas emission agreements of main countries all over the world, in recent years, all countries are vigorously developing clean energy, china also implements energy conservation and emission reduction in a planned way, and increases the scientific research input strength to the field of clean energy.
The electrolytic water technology is based on the principle of electrochemically decomposing water, and the water is decomposed into hydrogen and oxygen by utilizing renewable electric energy or solar energy driven by solar energy, which is considered as the most promising and sustainable hydrogen production way.
Because the anode generates hydrogen and the cathode generates oxygen when water (general alkaline liquid) is electrolyzed to prepare hydrogen, and in order to obtain pure hydrogen, the hydrogen preparation equipment adopts a diaphragm to separate the anode and the cathode so as to achieve the purpose of hydrogen-oxygen separation. At present, industrial waste gas is directly discharged into the air after hydrogen and oxygen are prepared, and the industrial waste gas is not further utilized. However, the industrial waste gas often contains alkaline components, and the alkaline components account for a small proportion of the industrial waste gas, but the industrial waste gas is produced for a large number of times and still pollutes the environment.
