摘要： Stacked bodies each formed by alternately stacking power generation cells and separators are fixed to an end plate, the separators each having a flow passage portion, a gas flow-in port, and a gas flow-out port. The end plate includes upper and lower end plates sandwiching the stacked bodies. The stacked bodies are arranged side by side and a first thermal deformation absorbing portion configured to absorb thermal deformation in a direction orthogonal to a stacking direction is formed between the stacked bodies. Fixing means for fixing the stacked bodies to the end plate fix at least outer peripheral portions of the stacked bodies arranged side by side to the end plate.

摘要： 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.
