Abstract

PURPOSE: To lower the hydrogen overvoltage and cost of the iron cathode by spray- coating the alloy or mixture composed of the specific ratios of skeleton metal such as iron and sacrifice metal soluble in alkalis to a conductive electrode substrate and alkali-eluting the sacrifice metal.
CONSTITUTION: The alloy or mixture composed of 10W50wt% of skeleton metal such as iron or composed primariy of iron and 90W50wt% of sacrificial metal soluble in alkalis selected from Al, Zn, Sn, Pb is spray-coated to a suitable thickness on the conductive substrate such as iron, mild steel or stainless steel having chemical resistance to electrolyte and the sacrifice metal in this coating is eluted by an alkali solution. The iron cathode obtained in this way has the hydrogen overvoltage equivalent to that of the conventional cathodes using expensive Raney-nickel, is free from the degradation in activity owing to the iron content depositing on the cathode and permits the use of inexpensive iron skeleton metals for cathodes for electrolysis of water, etc. which have hitherto been considered inadequate.
