摘要： 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.

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

摘要： A fuel cell stack includes: a first cell having a first fuel gas flow path; and a second cell having a second fuel gas flow path constructed to have a specific flow path structure having a higher potential for a decrease in concentration of a fuel gas than that of the first fuel gas flow path during power generation. A sensor is located on the second cell to detect a decrease in concentration of the fuel gas during power generation. In one exemplified structure, a groove formed on an anode separator of the second cell as the second fuel gas flow path has a restriction element to narrow the sectional area of flow passage. A hydrogen concentration sensor is located in a non-narrowed area in the downstream of the restriction element having a lower pressure level. Impurity gas discharge control discharges an anode off gas out of the fuel cell stack, in response to detection of a decrease in hydrogen concentration to or below a preset reference level by the hydrogen concentration sensor. This arrangement of the invention enables the effective use of the fuel gas and prevents deterioration of membrane electrode assemblies of the fuel cell stack by carbon oxidation in an anode dead end-type fuel cell system.

摘要： The membrane electrode assembly 100 has an electrolyte layer 10, a catalyst layer 20, and a member 15 impregnated with electrolyte which is arranged between the electrolyte layer 10 and the catalyst layer 20. At least part of the peripheral edge portion of the member 15 extends the outside the peripheral edge portions of the electrolyte layer and the catalyst layer 20. With this kind of constitution, it is possible to easily separate the electrolyte layer 10 or the catalyst layer 20 from the member 15 from the extended portion of the member 15. Consequently, it is possible to easily replace the electrolyte layer 10 and the catalyst layer 20.
