    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 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 membrane electrode assembly for a fuel cell, in which electrical resistance is minimized by including a current collector between a catalyst layer and a fuel diffusion layer inside electrodes to shorten the electron transfer distance, and in which corrosion of the current collector due to direct contact between the current collector and the catalyst in the catalyst layer is prevented by including an electrically conductive current collector-protecting layer between the current collector and the catalyst layer, and a fuel cell including the membrane electrode assembly which can stably exhibit constant performance for a prolonged period of time, and which has excellent efficiency due to low electrical resistance.
