Embodiment Construction

[0131] For reasons of convenience, the following detailed description refers to a method for preparing, manufacturing a battery, preferably a battery according to the invention.

[0132] We first state that the term porous as used herein in relation to a material such as a metal or metal alloy means that the material comprises pores or voids.

[0133] Consequently, the density of the porous material is correspondingly lower than the theoretical density of the non-porous material.

[0134] Within the meaning of the present invention, a support or layer is generally considered to be porous if its density is at most about 92% of the theoretical density.

[0135]The pores may be linked (connected) together or separated, but in the porous metal substrates of the cells of the present invention, as well as in other porous layers, the majority of the pores are linked (connected) and communicated. Hence the term open porosity is used.

[0136] More specifically, within the meaning of...

Abstract

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.

Description

technical field [0001] The present invention relates to metal supported electrochemical cells (or "electrochemical cells with metal substrates") or "MSCs". [0002] The present invention also relates to methods for making metal-supported electrochemical cells (or "metal-supported electrochemical cells"). [0003] The technical field of the present invention can be broadly defined as the field of new energy technology, especially aimed at reducing greenhouse gas emissions or promoting clean and renewable energy. [0004] The technical field of the invention can be defined more specifically as that of electrochemical cells, and more particularly metal supported electrochemical cells for high temperature applications generally from 600°C to 900°C. These electrochemical cells may be of the high temperature steam electrolyzer ("HTE") cells for the large-scale production of hydrogen, or of the high temperature fuel cell type equipped with hydrogen or various natural fuels such as n...
