US 2012/0258378 A1 · FUEL CELL

Abstract

A cell unit of a fuel cell includes a first membrane electrode assembly, a first metal separator, a second membrane electrode assembly, and a second metal separator. A resin frame member is provided integrally with an outer circumference of the first membrane electrode assembly. An oxygen-containing gas supply passage, a fuel gas supply passage, a coolant supply passage, an oxygen-containing gas discharge passage, a fuel gas discharge passage, and a coolant discharge passage extend through the resin frame member in a stacking direction. At each of both ends of the resin frame member in a longitudinal direction, a pair of projections are provided. The projections protrude toward both sides in a lateral direction.
