Abstract
The fuel cell single cell of the present invention includes: a fuel cell unit in which an anode electrode, an electrolyte layer and a cathode electrode are sequentially laminated; a separator; and a current collection assisting layer disposed between the cathode electrode of the fuel cell unit and the separator. The separator has protruded portions that are in contact with the current collection assisting layer to form gas channels between the separator and the current collection assisting layer. Further, at least a part of an end of the cathode electrode in a planar direction of the cathode electrode extends outward beyond an end of the current collection assisting layer in a planar direction of the current collection assisting layer.
