A fuel cell disclosed in Publication No. 5 is known. The fuel cells disclosed in these prior arts include forming a first electrode layer on the surface of a cylindrical porous support, forming a solid electrolyte layer on the surface of this first electrode layer, and forming the solid electrolyte layer on the surface of this first electrode layer. A second electrode layer is formed on the surface of the cylindrical support, with the inside of the cylindrical support serving as a first fuel gas passage, and the outside of the second electrode layer serving as a second fuel gas passage.

得るようにしている。By the way, the voltage generated by one fuel cell is approximately 1
volt, so a single fuel cell cannot supply sufficient power. Therefore, in the above-mentioned prior art, a large number of fuel cells are arranged in parallel, and the electrodes of adjacent fuel cells are connected in parallel or in series, so that sufficient power can be supplied.

接続している。[Problems to be Solved by the Invention] In the above-mentioned prior art, when connecting adjacent fuel cells in parallel or in series, the first or second electrodes or the first and second electrodes are connected at the ends of the fuel cells. If the electrode layers are connected in the longitudinal direction, the resistance increases and the efficiency deteriorates, so the electrode layers are connected along the length direction.

きない。By the way, the cylindrical porous support that forms the electrode layer and solid electrolyte layer of a fuel cell is manufactured by kneading a ceramic material with a binder, forming it into a cylindrical shape, and firing it. Since ceramic shrinks by about 20% during firing, the cylindrical support tends to bend after firing, and if used as is, there will be places where electrodes cannot be connected to each other. For this reason, the support is made thick in anticipation of the bending after firing, and the bending is corrected by grinding the support after firing. However, increasing the thickness of the support in anticipation of bending wastes material, and grinding after firing is cumbersome, and furthermore, increasing the length of the fuel cell increases the risk of bending and deflection. Since it becomes large, the length becomes about 50 cm at most, and the output voltage cannot be increased.
