CELL FOR FUEL CELLS, ITS MANUFACTURING METHOD, HALF CELL FOR FUEL CELL, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a cell for a fuel cell forming a boundary surface between a solid electrolyte layer substrate and a cathode and between the solid electrolyte layer substrate and an anode as wide as possible without enlarging the cell for the fuel cell.

SOLUTION: In the cell 10 for the fuel cell in which the anode 16 coming in contact with fuel gas is formed on one side of the solid electrolyte substrate 12, and a cathode 14 coming in contact with oxygen-containing gas is formed on the other side of the solid electrolyte substrate 12, the anode 16 and the cathode 14 are formed with a magnetic material layer comprising magnetic metal or its oxide, and the boundary surface between each magnetic material layer and the solid electrolyte substrate 12 comprising an electrolyte material which is a non-magnetic material is formed in an irregular recessed and projecting surface.
