    摘要: A hydrogen ionic conductive inorganic material having a layered structure, wherein a moiety containing a functional group with hydrogen ionic conductivity is introduced between layers of an inorganic material having a nano-sized interlayer distance. A polymer nanocomposite membrane including a reaction product of the hydrogen ionic conductive inorganic material and a conductive polymer, and a fuel cell using the same, are also provided. In the polymer nanocomposite membrane, a conductive polymer may be intercalated to a hydrogen ionic conductive inorganic material having a layered structure or products exfoliated from an inorganic material having a layered structure are dispersed in a conductive polymer.

    摘要: A proton conducting inorganic material having a layered structure in which a sulfonic acid group-containing moiety having proton conductivity is introduced in between the layers of an inorganic material having a nano-sized interlayer distance such that the sulfonic acid group-containing moiety is directly bound to the inorganic material via an ether bond. A polymer nano-composite membrane including the product of a reaction between the inorganic material having the sulfonic acid-containing moiety with a proton conducting polymer, and a fuel cell adopting the same, wherein the polymer nano-composite membrane has a structure in which a proton conducting polymer is intercalated between the layers of the proton conducting inorganic material having a layered structure, or a structure in which the product of exfoliating the proton conducting inorganic material having a layered structure is dispersed in a proton conducting polymer. The polymer nano-composite membrane can have a controllable degree of swelling in a methanol solution, and the transmittance of the polymer nano-composite membrane can be reduced

    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.
