Title:
MULTIPLE OXIDE FOR AIR POLE OF SOLID ELECTROLYTIC FUEL CELL AND FOR ELECTRIC COLLECTOR RAW MATERIAL, ITS MANUFACTURING METHOD AND SOLID ELECTROLYTIC FUEL CELL
Document Type and Number:
Japanese Patent JP2002053374
Kind Code:
A
Abstract:
To provide a multiple oxide for an air pole of a solid electrolytic fuel cell and for an electric collector raw material, which is restrained from causing shrinkage phenomenon due to the heat cycle when used in the solid electrolytic fuel cell and in which cracks and exfoliation can be restrained and which is high in sinterability and enhanced in electric conductivity, and to provide a method for manufacturing the multiple oxide and the long-life solid electrolytic fuel cell.
This multiple oxide for the air pole of the solid electrolytic fuel cell and for the electric collector raw material contains the multiple oxide represented by La1-x-yAxLnyMnzO3+δ (wherein A is Ca or Sr; Ln is Sm, Gd or Y; 0.3≤x≤0.6; 0≤y≤0.3; 1.5≤z≤4.5).
