A fuel cell, which can increase a ratio of an area of a power generation region to an area of a fuel cell unit to increase power per unit volume and unit weight of a fuel cell. The fuel cell includes an oxidizer electrode surrounding member provided at four corners of the fuel cell unit to incorporate atmospheric oxygen through an oxidizer intake formed at a gap of the oxidizer electrode surrounding member. The fuel cell further includes a through-hole which serves as a hydrogen gas supply path for each fuel cell unit and fastens the fuel cell units in a stacking direction formed inside the oxidizer electrode surrounding member. By aligning through-holes of end plates, separator, and fuel electrode seals with each other and by allowing a stack fastening component to penetrate through the through-holes, the whole is pressed and urged to be assembled.
