A gasket is arranged between a fastening portion of an end plate arranged at an end in a cell stacking direction of a cell stack of a fuel cell and a case covering a periphery of the cell stack. The gasket is configured to seal a gap between the fastening portion and the gasket and a gap between the case and the gasket. The gasket includes a base plate and an elastic material layer. The base plate has a slope section that connects an inner peripheral section and an outer peripheral section to each other. The inner peripheral section and the outer peripheral section are located at different positions in a thickness direction of the base plate. The slope section is inclined with respect to the inner peripheral section and the outer peripheral section.

A fuel cell stack, includes a plurality of fuel cells. Each fuel cell includes a shell, an anode and a cathode mounted in the shell. A liquid storage chamber used for storing electrolyte and a communicating part used for communicating the liquid storage chamber are provided in the shell of each fuel cell.
