Abstract
The invention relates to the technical electrochemistry, namely to an electrode for hydrogen electrolytic obtaining and a process for manufacturing thereof.The electrode, according to the invention, consists of a current-conducting substrate of porous carbon-fibrous material and of an active layer of porous cobalt-nickel-boron-palladium alloy.The process for electrode manufacturing includes deposition on the current-conducting substrate of the porous cobalt-nickel alloy from a solution, containing dimethylaminoborane, nickel and cobalt salts, with subsequent leaching of the nonmetallic component. It is carried out the catalytic activation with palladium of the porous surface of the carbon-fibrous material and chemico-catalytic deposition of the cobalt-nickel-palladium-boron alloy from the solution, which additionally contains palladium salt, potassium pyrophosphate, triethanolamine and 2-mercaptobenzothiazole, in the following component ratio, g/L:The alloy deposition is carried out at the temperature of 50...70°C and a pH of 6,5...10,0, and the leaching is carried out by treatment in the flux of a solution heated up to 40...50°C, during 3...5 min, the solution having the following component ratio, g/L:
