摘要： 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.

摘要： A fuel cell is formed by alternately stacking separators and sealing gasket-combined membrane electrode assemblies. Each sealing gasket-combined membrane electrode assembly includes a membrane electrode assembly and a sealing gasket portion. One of the sealing gasket portion and the separator has a protrusion formed on each face and extending in a stacked direction in which the separators and the sealing gasket-combined membrane electrode assemblies are stacked. The other of the sealing gasket portion and the separator has a recess in which the protrusion is fitted. The protrusions formed respectively on opposed faces of the successive sealing gasket-combined membrane electrode assemblies or the successive separators are located at different positions.

摘要： A fuel cell module, wherein slopes of a same angle θ relative to a bottom face are formed on both side faces to form a recessed groove in a tapered shape. Since the angle θ is provided to the side faces of the recessed groove, the exhaustion of gases from the accumulation of gasses to the outside can be assisted by the side faces with the angle θ more than in a case where the side faces of the recessed groove are formed in right angled shapes even if the accumulation of gases is produced between an adhesive agent and the inner surfaces of the recessed groove when first and second separators are joined to each other for modularization by covering the first separator on the second separator. Thus, the accumulation of the gases can be prevented from occurring.
