Title:
SOLID ELECTROLYTE FUEL CELL
Document Type and Number:
Japanese Patent JP2005174664
Kind Code:
A
Abstract:
To provide a solid electrolyte fuel cell in which strength and thermal shock resistance are improved and power generation characteristics are improved.
This is a solid electrolyte fuel cell provided with a single cell 1 laminated by a fuel electrode 3, the solid electrolyte 4 and an air electrode 5 in this order. On the outside of the fuel electrode in the single cell 1, a support body 2 composed of a composite porous body retracted of a constitutional material of the fuel electrode 3 in a pore of a metal porous material is laminated furthermore, and the air electrode 5 composition is expressed by a general formula: La1-xSrxCo1-yFeyO(3±δ). In the formula, 0.1≤x≤0.9, 0.1≤y≤0.9, and 0≤δ<1.
