    摘要: A proton conductive copolymer includes styrene repeating units that have proton conductive functional groups and dimethylsiloxane repeating units. A polymer electrolyte membrane includes the proton conductive copolymer and a fuel cell uses the polymer electrolyte membrane. The proton conductive copolymer has excellent chemical and mechanical properties, excellent ability to form membrane with dimethylsiloxane repeating units, and superior ion conductivity with styrene repeating units that have proton conductive functional groups. Polymer electrolyte membranes that have properties appropriate for the fuel cell electrolyte membrane can be obtained using the proton conductive copolymer. Fuel cells that have improved efficiencies can be obtained using the polymer electrolyte membrane.

    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.
