Abstract
Description
Technical Field

Water electrolysis hydrogen production is a relatively convenient method. Direct current is passed into an electrolytic cell filled with potassium hydroxide or sodium hydroxide, and water molecules undergo electrochemical reactions on the electrodes, decomposing into hydrogen and oxygen.
[0003] The water electrolysis hydrogen production equipment currently on the market has the defect of not being able to perform preliminary filtration on the water when it is used, which can easily cause too many impurities in the water to remain in the hydrogen production device, bringing adverse effects on the hydrogen production work; and the existing water electrolysis hydrogen production equipment generates heat during the chemical reaction when electrolyzing water to prepare hydrogen. The heat generated will increase the internal pressure of the reaction tank, so it is necessary to discharge the heat in the reaction tank in time. The existing reaction tanks mostly discharge heat through exhaust pipes. When the reaction tank works for a long time, the heat generated is not easy to dissipate in time. Therefore, we propose a new water electrolysis hydrogen production device. Utility Model Content
