ELECTRODE, ELECTRODE CATALYST COMPOSITION AND FUEL CELL

Japanese Patent JP2008270181

A

To provide an electrode suitable for increasing electromotive force in a fuel cell, particularly in a single chamber solid oxide fuel cell.

The electrode has Eh represented by formula (1) of -10 to 100 mV. Eh=E0-E3 (1) [Wherein, E0 is electrode potential showing when gas (only oxidative gas) having a hydrogen concentration of 0% is brought into contact with the electrode at room temperature, and E3 is electrode potential showing when mixture gas (hydrogen gas and oxidative gas) having a hydrogen concentration of 3 vol.% is brought into contact with the electrode at room temperature]. An electrode catalyst composition has a trivalent manganese-containing compound. The electrode has the electrode catalyst composition. The solid oxide fuel cell has the electrode. The single chamber solid oxide fuel cell has the electrode as a cathode and has an anode. The single chamber solid oxide fuel cell has the anode including gold and platinum.
