PURPOSE:To equalize the power generating property of each unitary fuel cell by blocking up the top of an inner spacer tube and also providing many ventilation holes, and supplying fuel gas from the base side. CONSTITUTION:Plural fuel cell simples 24 are arranged between the outer periphery of an inner spacer tube 22, top of which is blocked up and which has many ventilation ports at the cylindrical part, and the inner periphery of an outer spacer tube 23, and those are connected electrically. And in case that a fuel electrode 27 is formed around the fuel cell simple 24, if fuel gas is supplied from the base side into the inner spacer tube 22, the fuel gas blows off from the many ventilation ports, and fresh fuel gas, which is not yet used for reaction, is supplied to over the whole length of each fuel cell simple 24 arranged around the inner spacer tube 22, and the supply of fuel gas free of waste becomes possible. Hereby, the dispersion of fuel gas concentration decreases, and the power generating properties of each fuel cell simple is equalized. |
