Description

Technical Field

[0001] The present application relates to the field of hydrogen collection, and in particular to a hydrogen collection device for water electrolysis hydrogen production equipment. Background Art

[0002] Hydrogen production by water electrolysis is the use of electric current to decompose water into hydrogen and oxygen. In the electrolyzer, two electrodes are connected to the positive and negative power poles respectively, and water undergoes an oxidation-reduction reaction on the electrodes, with the negative electrode producing hydrogen and the positive electrode producing oxygen, which is then collected. During this process, it is important to control the current and voltage to ensure safe and efficient hydrogen production.

[0003] When producing hydrogen by water electrolysis, the incomplete separation of oxygen and hydrogen may occur due to imperfect equipment or process conditions, resulting in a certain amount of water vapor being produced along with the hydrogen.
