摘要： A fuel cell includes a membrane electrode assembly and a separator. The separator includes a reactant gas inlet manifold, a reactant gas outlet manifold, a reactant gas channel, an inlet connection channel, an inlet buffer portion, an outlet buffer portion, and an outlet connection channel. A pressure drop through the inlet buffer portion is less than a pressure drop through the reactant gas channel when a reactant gas flows from the reactant gas inlet manifold to the reactant gas channel. A pressure drop through the outlet buffer portion is less than a pressure drop through the outlet connection channel when the reactant gas flows from the reactant gas channel to the reactant gas outlet manifold.

摘要： A power generation unit of a fuel cell stack includes a first metal separator, a first membrane electrode assembly, a second metal separator, a second membrane electrode assembly, and a third metal separator. A first oxygen-containing gas flow field includes a plurality of wavy flow grooves. An outlet merging area is provided at the end of the wavy flow grooves on the outlet side. The outlet merging area is connected to a plurality of straight connection flow grooves. The groove depth of the straight connection flow grooves is smaller than the groove depth of the wavy flow grooves.

摘要： A resin frame equipped membrane electrode assembly includes a membrane electrode assembly and a resin frame member. The membrane electrode assembly includes a solid polymer electrolyte membrane and an anode, and a cathode sandwiching the solid polymer electrolyte membrane. The resin frame member is formed around the solid polymer electrolyte membrane. The outer end of an electrode catalyst layer of the cathode protrudes beyond the outer end of a gas diffusion layer, and the resin frame member includes an inner extension protruding toward the outer periphery of the cathode to contact the outer end of the solid polymer electrolyte membrane. The inner extension of the resin frame member has an overlapped portion overlapped with the outer end of the electrode catalyst layer.
