Abstract: A fuel cell includes: an electrolyte membrane; a cathode positioned on a first surface of the electrolyte membrane; an anode positioned on a second surface of the electrolyte membrane; a cathode-side sealant positioned on a surface of the cathode different from the electrolyte membrane side of the cathode; an anode-side sealant positioned on a surface of the anode different from the electrolyte membrane side of the anode; a cathode-side separator positioned on a surface of the cathode-side sealant different from the cathode side of the cathode-side sealant; and an anode-side separator positioned on a surface of the anode-side sealant different from the anode side of the anode-side sealant. The anode-side separator has a projection on a surface stacked on the anode-side sealant, or the cathode-side separator has a projection on a surface stacked on the cathode-side sealant.

Abstract: A fuel cell stack includes: a cell stack including separator plates, and cells each placed between the separator plates; a pair of current collectors that hold external lateral surface of the cell stack in a cell-stacking direction; and a pair of end plates that hold the pair of current collectors from outsides of said current collectors in the cell-stacking direction, wherein the cell stack possesses (i) at least one first opening formed on one external lateral surface of said cell stack, said one external lateral surface located along a direction perpendicular to the cell-stacking direction, (ii) a second opening formed on an external lateral surface of the cell stack opposite to the one external lateral surface, and (ii) at least one passage that extends through an inside of the cell stack from the at least one first opening or the at least one second opening.
