Process for manufacturing elementary electrochemical cells for energy- or hydrogen-producing electrochemical systems, in particular of SOFC and HTE type

摘要

The invention relates to a process for manufacturing at least one elementary electrochemical cell comprising a first and a second electrode between which an electrolyte is intercalated, said first and second electrodes and said electrolyte being in the form of layers, which process is characterized in that it comprises: a) producing at least one structure comprising a layer of a powder of a first electrode material and a layer of a powder of a second electrode material between which a layer of a powder of an electrolyte material is intercalated; and b) simultaneously sintering all the powder layers by an electric field sintering. Applications: manufacture of energy- or hydrogen-producing electrochemical systems, in particular solid oxide fuel cells (SOFCs) or high temperature electrolysers cells (HTEs).
