An electrode ( 1 ) for fuel cell according to the present invention comprises electron-conducting particles ( 5 ), and fibrous oxide particles ( 3 ). In the electrode ( 1 ), the ratio represented by the following formula (I) is within a range from 5 to 25, and the ratio represented by the following formula (II) is within a range from 1 to 10: average major axis of the oxide particles ( 3 )/average major axis of the electron-conducting particles ( 5 ) (I), and thickness of the electrode ( 1 )/average major axis of the oxide particles ( 3 ) (II). A large number of oxygen ion-conducting paths can thereby be formed in the electrode ( 1 ) to increase three phase zones, thus permitting electrons to be efficiently taken out therefrom. Further, a fuel cell ( 10 ) with high output and excellent power generation efficiency can be obtained by using the electrode ( 1 ) of the present invention. |
