The invention relates to a power generation cell and a fuel cell stack. A power generation cell of a fuel cell stack includes an MEA with a resin frame, and first and second metal separators. In the power generation unit cell, P1gt is satisfied; p2gt, P2gt; and P3 relationship in which P1 represents a first surface pressure applied to the resin frame member by the first sealing portion and the second sealing portion, P2 represents a second surface pressure applied to the overlapping portion by the first supporting portion and the second supporting portion, and P3 represents a third surface pressure applied to the power generation region by the first flow path forming protrusion and the second flow path forming protrusion. 本发明涉及发电单电池和燃料电池堆。燃料电池堆的发电单电池包括带树脂框的MEA以及第一金属隔板和第二金属隔板。在发电单电池中，满足P1>P2>P3关系，其中，P1表示第一密封部和第二密封部施加于树脂框构件的第一表面压力，P2表示第一支承部和第二支承部施加于重叠部的第二表面压力，P3表示第一流路形成突起件和第二流路形成突起件施加于发电区域的第三表面压力。
