Document Type and Number:
WIPO Patent Application WO/2017/188421
Kind Code:
A1
Abstract:
Provided are an electrode for electrolysis of which durability against a reverse current is excellent, and a method capable of manufacturing the electrode for electrolysis at low cost. This electrode for electrolysis 130 is provided with: a conductive substrate 132 on which a catalyst layer is formed; and a reverse current absorbing body 134 separably combined with the conductive substrate 132, wherein the reverse current absorbing body 134 is composed of a sintered body including nickel. This manufacturing method of the electrode for electrolysis 130 includes: a sintered body forming process for sintering a raw powder composed of any one of Raney nickel alloy particles containing metal elements soluble in nickel and alkali, metal nickel particles, and a mixture of the Raney nickel alloy particles and the metal nickel particles, and obtaining a sintered body; and a combining process for combining the sintered body to the conductive substrate 132.
