PURPOSE:To obtain a high output fuel cell of small inner resistance by providing a conductive supporting body with a function as connecting tools for electrically connecting plural single cells, which supporting body keeps plural single cells being connected in parallel to each other. CONSTITUTION:Each single cell 1 is held while in contact with the inner peripheral face of the tubular portion 8c of a supporting body 8, and a stack comprises five single cells 1 connected in parallel to each other. In each stack, a plate- shaped portion 8a located on the center side of the single cell 1 is integrated with the tubular portion 8c of adjacent other stack, and also the tubular portion 8c surrounding the single cell 1 is integrated with the plate-shaped portion 8a surrounded by the single cell 1 in the other stack, and so plural stacks are connected in series to each other by putting each plate-shaped portion 8a as one electrode and each tubular portion 8c as the other electrode in conduction to each other sequentially. As a result, the supporting body is used as parts with integrated structure serving also as connecting tools for the group of single cells, and besides the cross area where current are caused to flow is wide so that the inner resistance is reduced and the current passage is shortened. High output is thus achieved. |
