FUEL CELL WITH POWER GENERATING PORTION

摘要

A fuel cell (10) including separators (1, 2) opposing each other and squeezing a power generating reaction portion (5). Each of the separators (1, 2) includes a gas passage (3, 4), a gas passage dividing rib (6), and a protrusion (7) formed in the gas passage. In a first separator (1, 2), which is an at least one separator (1, 2) of the separators opposing each other via the power generating reaction portion (5), at a region (S) of the first separator (1, 2) opposing a gas passage dividing rib of a second separator (2, 1), which is a separator opposing the first separator (1, 2), a squeezing rib (8) is formed and replaces the protrusion (7). The squeezing rib (8) and the gas passage dividing rib (6) of the second separator (2, 1) squeezes the power generating reaction portion (5). At the region (S) of the first separator (1, 2), a contact area (S 1) of the squeezing rib (8) with the power generating reaction portion (5) is adapted to be larger than a contact area (S2) of the protrusion (7) of the first separator (1, 2) with the power generating reaction portion (5) in a case where the protrusion (7) were formed without forming the squeezing rib (8).
