PROBLEM TO BE SOLVED: To take out electric energy efficiently by keeping lead resistance low for leading electric energy to an external circuit. SOLUTION: A fuel electrode 1, a solid electrolyte 3, an air electrode 5 are arranged in the order from the inside in coaxial layer. A conductive felt 17 directly contacting the air electrode 5 and an opposing surface of a cathode conductive material 11 is arranged between the outer circumference of the outermost air electrode 5 and the cathode conductive material 11 connecting to a positive side of an external circuit and continuing in a longitudinal direction. The opposing surfaces of the air electrode 5 and the cathode conductive material 11 are made flat surfaces 13, 15 nearly in parallel to maintain uniform and sure contact pressure over the whole area of the conductive felt 17. |
