Abstract

The invention relates to a method for observing bubbles in hydrogen production equipment and a proton exchange membrane electrolyzer. The hydrogen production equipment includes: an electrolytic cell, the electrolytic cell includes an anode assembly, a cathode assembly and a proton exchange membrane assembly, the anode assembly and the cathode assembly are respectively arranged on both sides of the proton exchange membrane assembly, and the anode assembly There is an observation structure for the light to enter the anode assembly; a light supplement device, the light supplement device includes a light source assembly and a lens assembly, and the incident light emitted by the light source assembly passes through the lens assembly and is perpendicular to the first direction Injecting into the observation structure; a photographing device, the photographing device is used to photograph the bubbles in the anode assembly, and the outgoing light reflected by the bubbles is vertically incident into the photographing device. In this device, the photographing effect of the bubbles generated in the electrolytic cell is better, and the photographed bubbles are relatively clear.

Description

technical field [0001] The invention relates to the technical field of water electrolysis, in particular to hydrogen production equipment and a bubble observation method in a proton exchange membrane electrolyzer. Background technique [0002] As a new type of energy, hydrogen energy is less likely to pollute the environment and is more efficient, so it has received more and more attention. In related technologies, hydrogen is mainly obtained by electrolyzing water through a proton exchange membrane. When water is electrolyzed, after water flows in from the anode side, oxygen and hydrogen ions are generated at the anode. Therefore, a gas-liquid two-phase flow of oxygen and water will appear on the anode side, thereby forming bubbles. In this process, the research on the size, growth law and movement state of the bubbles is helpful to improve the working performance of the electrolyzer. Therefore, a photographing device is installed in the usual hydrogen production equipmen...
