Abstract: A fuel cell according to one mode includes a plurality of stacked cell units, each cell unit including at least an electrically conductive interconnector having a front surface and a back surface; a pair of connection members which are electrically connected to the interconnector; a single cell which includes an anode, a cathode, and an electrolyte therebetween and which is electrically connected to the connection members; and a separator having an opening which is connected to an outer peripheral portion of the single cell, the cell units being clamped together in a stacking direction, wherein the connection member on an anode side or a cathode side of the single cell of at least one cell unit of the cell units has a thickness different from that of the connection member on the anode side or the cathode side of the single cell of another cell unit.
