Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide the manufacturing method of an anode for a solid oxide fuel cell capable of surely sintering without damaging adhesion between an electrolyte and the anode, enhancing conductivity, and also enhancing output performance and durability at low cost; and to provide the solid oxide fuel cell using dimethyl ether which is a clean energy source as direct fuel and capable of operating at intermediate temperature of 400-700°C. SOLUTION: An oxide developing proton conductivity at 400-700°C is used as an electrolyte, and the anode made of iron or an iron oxide is obtained by mixing iron or iron oxide powder with an organic solvent to prepare slurry, coating the slurry on the electrolyte, and baking iron or iron oxide. When iron oxide is used, after baking, the iron oxide is reduced in reducing atmosphere such as hydrogen gas at temperature near to cell operation temperature. COPYRIGHT: (C)2008,JPO&INPIT
