Abstract: A fuel cell includes a plurality of cells each of which includes a solid electrolyte layer having an oxygen electrode on one side thereof and a fuel electrode on the other side thereof, the cells being stacked one above another with a predetermined space therebetween so as to form an oxygen-containing gas passage facing the oxygen electrode and a fuel gas passage facing the fuel electrode, a passage forming member interposed between the adjacent cells to section the oxygen-containing gas passage and the fuel gas passage, the passage forming member having electric conductivity; and a conductive member charged within a space between the passage forming member and the fuel electrode or between the passage forming member and the oxygen electrode, the conductive member having a porous construction to allow passage of gas therethrough as well as flexibility. The adjacent cells are electrically conductively connected with each other via the passage forming member and the conductive member.
