A fuel cell includes: a membrane electrode assembly of a flat plate shape including an electrolyte membrane and an electrode catalyst layer, the membrane electrode assembly having a first side intersecting a flow pathway of a reactive gas on a surface of the fuel cell and a second side differing from the first side; a frame member of a flat plate shape including an opening part for arrangement of the membrane electrode assembly, the opening part having a first frame side corresponding to the first side and a second frame side corresponding to the second side; and an adhesive member for bonding between an outer periphery of the membrane electrode assembly and an inner periphery of the frame member. The thickness of the adhesive member in an area from an inner peripheral edge at the second frame side toward a center of the frame member may be greater than the thickness of the adhesive member in an area from an inner peripheral edge at the first frame side toward the center of the frame member.

Fuel cell and method of manufacturing fuel cell

In a fuel cell having a separator in which main cooling water channels are formed, a separator for another unit cell stacked on the cooling water channel formation surface side of the separator, and a second sealing member interposed between the separators and to seal a cooling medium flowing in the main cooling water channels, an outer peripheral rib for regulating the flow of cooling water to the second sealing member side is provided inside relative to the second sealing member in the separator surface direction in order to improve the efficiency of cooling with the cooling medium.

Fuel cell and fuel cell separator

A fuel cell system includes a fuel cell, anode gas pressure adjusting means that adjusts the pressure of an anode gas supplied to the fuel cell, and cathode gas pressure adjusting means that adjusts the pressure of a cathode gas supplied to the fuel cell. The system further includes pressure control means that sets the pressure of the anode gas that is supplied when starting the fuel cell higher than the pressure of the anode gas that is supplied during power generation in the fuel cell, and controls the anode gas pressure adjusting means and the cathode gas pressure adjusting means so that a cathode gas pressure increase is started in accordance with the start of an anode gas pressure increase when the pressure of the anode gas is increased to the set pressure.

Fuel cell system

A membrane electrode assembly according to the invention includes a solid polymer electrolyte membrane and an electrode joined to each of two sides of the solid polymer electrolyte membrane. The solid polymer electrolyte membrane is such that some or all of the protons included in the entire solid polymer electrolyte membrane, a band region, or a non-power generating region are ion exchanged with one or more cations selected from among complex cations, class four alkylammonium cations, and high valence cations. In addition or alternatively, the solid polymer electrolyte membrane includes an organo-metalloxane polymer obtained by impregnating the entire solid polymer electrolyte membrane, the non-power generating region, or the band region with an organo-metalloxane monomer that includes an ammonium cation or a class four ammonium cation at its terminus and then hydrolyzing and polycondensing the organo-metalloxane monomer.

Membrane electrode assembly and polymer electrolyte membrane fuel cell

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.

Fuel cell

A fuel cell () includes a lamination () of a plurality of unit cells (), current collector plates () arranged at both ends of the lamination (), end platesrespectively provided outside the current collector plates () with 5 insulating plates () interposed therebetween, and fastening members () for fastening the end plates () in the laminating direction to apply desired pressing force to the lamination (). A barcode () corresponding to particular information relating to a unit cell () is provided on the exposed side surface of a separator () of the unit cell (). According to this fuel cell (), the barcodecan be easily read requiring no disassembly of the fuel cell (). Moreover, as the information relating to the fuel cell can be obtained from the barcode (), the information that cannot be determined from outer appearance can be obtained, resulting in improved service operations.

Fuel cell component having a retrieval code

A fuel cell module, wherein slopes of a same angle &#x3b8; relative to a bottom face are formed on both side faces to form a recessed groove in a tapered shape. Since the angle &#x3b8; 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 &#x3b8; 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.

Fuel cell module

A fuel cell separator is pressed so that one side thereof defines a gas flow channel and that the other side thereof defines a coolant flow channel. A width dand a cross-sectional area Sof the gas flow channel and a width dand a cross-sectional area Sof the coolant flow channel satisfy a relationship: d&#x2267;dor a relationship: S&#x2267;S.
