    摘要: A fuel cell separator (2) of the present invention has a turn portion of a serpentine-shaped reaction gas passage region (101). In the turn portion, a recessed portion (28) is defined by an outer end (28a) of the turn portion and oblique boundaries between the recessed portion (28) and a pair of passage groove group. In the turn portion, a plurality of protrusions (27), which vertically extend from a bottom face of the recessed portion (28) and are arranged in an island form, are disposed such that one or more protrusions (27) form a plurality of columns lined up and spaced apart from each other with a gap in a direction in which the outer end (28a) extends and one or more protrusions (27) form a plurality of rows lined up and spaced apart from each other with a gap in a direction perpendicular to the direction in which the outer end (28a) extends; and the plurality of protrusions (27) are configured such that flow of the reaction gas is guided by protrusions (27) forming one row in the direction in which the outer end (28a) extends and is disturbed by protrusions forming a row adjacent the one row.

    摘要: A polymer electrolyte fuel cell comprises an electrolyte membrane-electrode assembly, a pair of conductive separator plates sandwiching the electrolyte membrane of the electrolyte membrane-electrode assembly, and a pair of sealing means sealing between the electrodes of the electrolyte membrane-electrode assembly and the separator plates. The pair of sealing means is constituted by combination of a flat sealing member having a flat portion in flat contact with the electrolyte membrane and of a linear sealing member having a rib in linear contact with the electrolyte membrane, and at least part of the rib is in the form of falling in the direction to the electrode when the electrolyte membrane, the pair of electrodes and the pair of separator plates are stacked to be cramped. This makes it possible for the fuel cell to have an excellent sealing property and a stable output characteristic.

    摘要: A method of producing an electrode having a high performance in a simple and convenient manner which does not require the use of any of the medium, surfactant and pore-producing agent is disclosed. In the disclosed method, a layer including a catalyst powder is formed on a surface of a polymer electrolyte film or a porous conductive electrode substrate by supplying an electrostatically-charged catalyst powder to the polymer electrolyte film or the porous conductive electrode substrate. Alternatively, a layer including a catalyst powder is formed on a surface of a polymer electrolyte film or a porous conductive electrode substrate by spraying the catalyst powder on the surface of the polymer electrolyte film or the porous conductive electrode substrate together with a carrier gas, thereby to cause the catalyst powder to adhere to the surface.
