Abstract
PURPOSE: To obtain a cathode for electrolyzing water having remarkably lower hydrogen overvoltage than a conventional cathode during electrolysis as well as high mechanical strength by forming an iron plated layer contg. P on at least part of the surface of the substrate metal of a cathode.
CONSTITUTION: A cathode for electrlyzing water is manufactured by forming an iron plated layer contg. P on at least part of the surface of a cathode body made of material such as iron, Ni or Ti which is used as the base material of a cathode in general. To an iron plating bath contg. water soluble iron salt by 0.1W1.7mol/l as ferrous ions are added 0;1W1mol/l hypophosphite ions such as sodium hypophosphite, and an ordinary water soluble buffer or a complexing agent is added preferably. This plating bath is adjusted to 1.5W9pH, and said cathode base material is plated at 20W90°C and 2W20A/dm2 current density. It is desirable to prevent the oxidation of ferrous ions by carrying out the plating in a nonoexidizing atmosphere.
