ELECTROCHEMICAL CELL HAVING A METAL SUBSTRATE, AND METHOD FOR MANUFACTURING SAME

摘要

The invention relates to an electrochemical cell having a metal substrate, including: a porous metal substrate (41) comprising a first main surface and a second main surface; a porous thermomechanical adaptation layer (42) on said second main surface; a porous layer, which acts as a barrier for the diffusion of chromium (43), on said porous thermomechanical adaptation layer, said porous layer, which acts as a barrier for the diffusion of chromium, is made of stabilized zirconium and/or substituted cerine and a mixed oxide having a spinel structure; a porous hydrogen electrode layer (44) on said porous layer which acts as a barrier for the diffusion of chromium; a dense electrolyte layer (45) on said porous hydrogen electrode layer; a dense or porous (46) layer, which acts as a reaction barrier, on said dense electrolyte layer (45); a porous oxygen or air electrode (47) layer on said layer, which acts as a reaction barrier (46). The invention also relates to a method for manufacturing an electrochemical cell having a metal substrate, including a step of simultaneously sintering the raw substrate and all of the predeposited raw layers.
