| 摘要 |
A cathode for use in the electrolysis of acid solutions, comprising an electrically conductive substrate, a sprayed coating layer containing at least 10% by weight of W, WC or a mixture thereof on the substrate and an impregnated coating layer comprising a mixture of a cathode active substance and an acid-resistant fluorine-based resin on the external surface of the sprayed coating layer, and a process for the production of such a cathode. The cathode has very superior hydrogen overvoltage characteristics and durability, and is very suitable for use in the electrolysis of acid solutions. |
