<p><P>PROBLEM TO BE SOLVED: To provide a method of producing an electrode, which has high durability and high hydrogen-generating catalysis and is used for alkaline water electrolysis. <P>SOLUTION: The electrode comprises 25-50 g/L of nickel sulfate hexahydrate, 30-100 g/L of sodium tungstate dihydrate, 15-80 g/L of thiourea, 60-120 g/L of citric acid anhydrate or sodium citrate dihydrate, and a stress reliever as an additive. The electrode is produced by using Ni-W-S alloy having pH of 3-6, to thereby form an amorphous or microcrystalline Ni-W-S alloy film 2 on a substrate 1. In that case, the stress reliever is preferably sulfosalicylic acid, and the Ni-W-S alloy film preferably contains 3-15 mass% of W, 15-30 mass% of S, and the balance Ni with inevitable impurities. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
