Abstract
A fuel cell including separators opposing each other and squeezing a power generating reaction portion. Each of the separators includes a gas passage, a gas passage dividing rib, and a protrusion formed in the gas passage. In a first separator, which is an at least one separator of the separators opposing each other via the power generating reaction portion, at a region of the first separator opposing a gas passage dividing rib of a second separator, which is a separator opposing the first separator, a squeezing rib is formed and replaces the protrusion. The squeezing rib and the gas passage dividing rib of the second separator squeezes the power generating reaction portion. At the region of the first separator, a contact area of the squeezing rib with the power generating reaction portion is adapted to be larger than a contact area of the protrusion of the first separator with the power generating reaction portion in a case where the protrusion were formed without forming the squeezing rib.
