| 摘要 |
The present application provides a fuel battery by which a loss due to electric resistance in a cathode, an electrolyte and an anode is decreased and which comprises a plurality of unit fuel cells each having the cylindrical anode, the cylindrical solid electrolyte in contact with the anode and the cylindrical cathode in contact with the cylindrical solid electrolyte, with the plurality of unit fuel cells being connected to each other with the interposition of connectors, the fuel battery being characterized in that the thickness of the anode is smaller with distance from the portion thereof connected to the cathode of the adjacent fuel cell, and the thickness of the cathode is smaller with distance from the portion thereof connected to the anode of the other adjacent fuel cell.
