1, less corrosive. When metal or alloy is used as cathode, because it works at relatively negative potential, it can often play a cathodic protection role and reduce corrosion.

2. Green energy saving. Water electrolysis cathode plate takes water as electrolyte, which is low in cost and non-volatile, so using water electrolysis cathode plate can save energy and cost.

3. Green and environmental protection. The cathode plate of water electrolysis does not contain harmful substances, and the pollution to the environment can be reduced by using the cathode plate of water electrolysis.
