    摘要: A fuel cell includes a cathode, an anode, an electrolyte membrane interposed between the cathode and the anode, and a porous layer containing a moisture retentive material. The anode includes an anode catalyst layer adjacent to the electrolyte membrane and an anode diffusion layer adjacent to the anode catalyst layer, and the porous layer is disposed between the anode catalyst layer and the electrolyte membrane. The performance of the fuel cell can be stably maintained even when a fuel supply is temporarily interrupted due to a malfunction of a pump or clogging of a fuel channel.

    摘要: A fuel cell system is provided with a first separation layer and a buffer solution layer disposed between a liquid-phase fuel storage layer and an anode of a membrane electrode assembly. A vapor-phase fuel is transferred to the buffer solution layer through the first separation layer, condensed, and diluted to produce a liquid-phase fuel with a low concentration in the buffer solution layer, and the low concentration liquid-phase fuel is supplied to the membrane electrode assembly. A second separation layer may be interposed between the first separation layer and the fuel storage layer. Fuel is supplied by a passive supplying method so that the system can be small with a high efficiency and unnecessary power consumption can be prevented. The fuel cell system can be operated regardless of orientation.

    摘要: The invention provides and a highly-dispersed supported catalyst that has a reduced average particle size of catalytic metal particles and is also supported by a porous support material. A method of preparing a supported catalyst that can reduce the average particle size of catalytic metal particles supported by a support material includes first mixing a charged support material with a solution containing a polymer electrolyte having a charge opposite to that of the support material to adsorb the polymer electrolyte on the support material. Next, the support material having the polymer electrolyte adsorbed thereon is mixed with a solution containing a catalytic metal precursor ion having a charge opposite to that of the polymer electrolyte to adsorb the catalytic metal precursor ion on the support material having the polymer electrolyte adsorbed on it. Finally, the catalytic metal precursor ion adsorbed on the support material having the polymer electrolyte adsorbed thereon is reduced to a catalytic metal in a reducing solution.

    摘要: A nanocomposite electrolyte membrane capable of suppressing cross-over of a polar organic fuel and a fuel cell using the nanocomposite electrolyte membrane are provided. The nanocomposite electrolyte membrane for a fuel cell includes a polymer having cation exchange groups and silicate nanoparticles dispersed in the polymer, the silicate nanoparticles having a layered structure, and the silicate nanoparticles being intercalated with the polymer, or layers of the silicate nanoparticles being exfoliated. The nanocomposite electrolyte membrane has an improved ability to suppress permeation of polar organic fuels, such as methanol, and appropriate ionic conductivity. In addition, a fuel cell with the nanocomposite electrolyte membrane can effectively prevent cross-over of methanol used as a fuel, thereby providing improved working efficiency and extended lifespan.
