To provide a fuel battery that has stable power generation performance, of which the maintenance is performed easily, by which startup time is reduced, and that can be easily manufactured with a simple structure.

A fuel battery cell 62 and a gas tank 58a that is provided with one end part in the axial length direction of the fuel battery cell 62 and in which the plurality of fuel battery cells 62 are erected are housed in the same chamber of a housing container, gas passing from the gas tank 58a to the inside of the fuel battery cell 62 and gas passing between the fuel battery cells 62 are reacted and burned in the vicinity of the tip of the fuel battery cell 62, and the tip of the fuel battery cell 62 is a non-power generation part A.
