The invention belongs to the technical field of water
electrolysis, and relates to a novel water
electrolysis hydrogen production process. The process comprises: inserting a
metal compound or a metalcompound composite
nonmetal anode and
cathode into an
electrolyte, and respectively connecting the
anode and the
cathode with the positive
electrode and the negative
electrode of a power supply; turning on a power switch so that
hydrogen bubbles are generated around the
cathode, and a reversible oxidation reaction occurs on the
anode without generation of bubbles; when no bubbles are generated onthe cathode, turning off the power switch; heating the
electrolyte to 50-120 DEG C, and carrying out anodic reduction to release
oxygen bubbles. According to the process, an electrochemical-chemical two-
step method is adopted to decompose water, and an
oxygen evolution reaction of the anode and a
hydrogen evolution reaction of the cathode are separately carried out from the aspect of time, so thata diaphragm is omitted, the cost is greatly reduced, the problems of mixing and separation of
oxygen and hydrogen are avoided, high-purity hydrogen is easier to prepare, the purification cost is reduced, and the product quality is improved.
