Abstract: In a cell stack of fuel cells according to the present invention, an output power density is measured at each of an upstream-side electricity generating section, which is located at an upstream-side of flow of fuel, and a downstream-side electricity generating section located at a downstream-side thereof. If the voltage at the upstream-side is higher than that at the downstream-side, a control operation to increase the concentration of fuel is performed. Conversely, if the voltage at the upstream-side is lower, a control operation to decrease the concentration of fuel is performed. Controldirected tofuelconcentration maximizing electricity generating efficiency may be implemented by repeatedly performing such control operations. There is no necessity for providing a concentration sensor in each of the generating sections. Consequently, simplification of configuration of and reduction in the size of the fuel cell may be achieved.

Abstract: Catalytic electrodes, and their production process, as well as electrochemical devices and their fabrication process are provided. The catalytic electrode includes a catalyst layer, which contains an electrolyte composed of a solid polymer such as polytetrafluoroethylene and also contains catalyst particles such as Pt. The solid polymer electrolyte has a crosslinked structure. The catalytic electrode is produced by forming the catalyst layer with the solid polymer and catalyst contained therein, and exposing the catalyst layer to radiation to crosslink the solid polymer and to bond side chains to the solid polymer, and further to introduce into the side chains ion dissociative groups.

Abstract: A method for generating hydrogen gas, an apparatus for producing hydrogen gas, and an energy conversion system, which are so designed as to generate hydrogen extremely efficiently without the help of catalyst are provided. The hydrogen gas is generated by decomposing a metal hydride in a mixture composed of said metal hydride, water, and a second solution which has a pH value lower than that of the aqueous solution of said metal hydride wherein the metal hydride is represented by a formula: alpha z(1-x) beta zx [BH y ], where alpha and beta are mutually different elements selected from Groups 1A, 2A, and 2B of the periodic table; and x, y, and z are defined respectively by 0

Abstract: A method for driving a fuel cell power generating equipment that can supply a diluted fuel having an optimum concentration to a power generating part without necessity of performing any absolute concentration measurement by use of a sensor or the like. A fuel cell power generating equipment that is driven by that driving method. The change in output voltage of the power generating part is observed in accordance with the fuel flow rate of the diluted fuel, whereby the diluted fuel can be always adjusted such that it has an optimum concentration, without necessity of performing any absolute concentration measurement by use of a sensor or the like. Moreover, this driving method can provide the most effective power characteristic and the most effective power generation efficiency in accordance with the status of a load and that of the fuel cell power generating equipment.
