Abstract

CATODO ADECUADO PARA UTILIZAR EN UN PROCESO ELECTROQUIMICO EN EL QUE SE DESPRENDE HIDROGENO (POR EJEMPLO EL PROCESO CLORO-ALCALI) EN EL QUE EL CATODO CONSTA DE UN SUSTRATO ELECTROCONDUCTOR (1) HECHO DE UN METAL NO-FERREO O QUE TIENE UN RECUBRIMIENTO COHERENTE DE UN METAL NO-FERREO SOBRE EL CUAL SE COLOCA UN ELECTROCATALIZADOR (4) QUE CONSTA DE PLATINO Y RUTENIO Y DONDE EL CATODO SE HACE MAS RESISTENTE AL ENVENENAMIENTO POR UNA POSICION DE ORO O PLATA Y, OPCIONALMENTE UNA DEPOSICION ULTERIOR DE PTFE. EL CATODO ES PARTICULARMENTE RESISTENTE AL ENVENENAMIENTO CON HIERRO.
