Abstract

Inventia prevede un electro avînd o acoperire (învelis) din material ceramic electrocatalitic pe substraturi de metal, efectiv incompatibile, prin recurgerea la utilizarea unei pre-acoperiri sau interstrat de ancorare aplicat pe substratul metalic, în mod avantajos, prin electrodepunere galvanica, preacoperirea respectiva constînd, în general, dintr-o matrice metalica inerta continînd particulele unui material ceramic care de preferinta, este compatibil sau chiar isomorf fata de materialul ceramic, constituind acoperirea electrocatalitica de suprafata sau externa. Adeziunea la substratul metalic si conductivitatea electrica prin acoperire, rezulta a fi prin aceasta mult ameliorate. Electroliza clorurii de sodiu în celulele prevazute cu electrodul din inventia prezenta este mai eficienta si mai putin problematica.
