ANODE SUPPORTING SUBSTRATE FOR SOLID OXIDE FUEL CELL AND PROCESS FOR PRODUCING THE SAME

摘要

An anode supporting substrate for fuel cell excellent in redox resistance, comprising 40-80 mass% of conductive components (A) and 20-60 mass% of skeletal components (B) with a porosity of 20-50%, and having, in the mapping photograph, by an energy dispersive system (EDS) employing an energy dispersive X-ray analyzer, of the cross-section of the substrate, a part [AB] where conductive components (A) and skeletal components (B) are mixed and a specified number of scattered parts [A] where only unmixed conductive components (A) exist, wherein the scattered parts [A] have maximum major diameter of 8-100 mum and an average major diameter of 5-50 mum.
