| 摘要 |
A low cost, robust bi-tubular solid state electrochemical device including a first porous, sintered support tube of a non-noble transition metal, a non-noble transition metal alloy and a cermet incorporating one or more of a non-noble transition metal and a non-noble transition metal alloy and having successive layers of a first porous electrode, a dense electrolyte and a second porous electrode, said successive layers disposed radially on the interior surface of said first porous, sintered support tube or disposed radially on the exterior surface of the first porous, sintered support tube and a second porous, sintered tubular member of a non-noble transition metal, a non-noble transition metal alloy and a cermet incorporating one or more of a non-noble transition metal and a non-noble transition metal alloy formed, deposited, or placed in electrical contact with the second porous electrode. The bi-tubular device of the present invention may comprise a solid oxide fuel cell or a solid oxide electrolyzer cell.
