Title:
ELECTROCHEMICAL CELL
Document Type and Number:
WIPO Patent Application WO/2023/127246
Kind Code:
A1
Abstract:
An electrochemical cell (1) comprises: a metal support (2) constituted from an Fe-based alloy; a cell part (3); and a bonding layer (4). The cell part (3) is provided with: a solid electrolyte layer (30) having oxygen ion conductivity; a first electrode layer (31) disposed on one surface side of the solid electrolyte layer (30); and a second electrode layer (32) disposed on the other surface side of the solid electrolyte layer (30). The bonding layer (4) bonds the metal support (2) and the first electrode layer (31). The bonding layer (4) is constituted from an oxide having electron conductivity and containing at least one metal element from among the alloy elements of the Fe-based alloy constituting the metal support (2). The bonding layer (4) is inclined so that the concentration of at least one of said metal elements decreases from the metal support (2) side toward the first electrode layer (31) side.
