ELECTRODE FOR A FUEL CELL COMPRISING A CATALYST LAYER AND A GAS DIFFUSION LAYER INTEGRATED WITH ONE NANOFIBER WEB AND METHOD OF PREPARING THE SAME AND FUEL CELL USING THE SAME

摘要

The present invention relates to an electrode for a fuel cell which comprises a carbonized or graphitized nanofiber web, which is subjected to water-repellent treatment on one side, both sides or as a whole, being used as a gas diffusion layer; and a catalyst layer that is formed by directly fixing a platinum-based catalyst to, in the case of when only one side of the nanofiber web is subjected to the water-repellent treatment, the other side thereof, or to, in the case of when both sides or the whole of the nanofiber web are subjected to the water-repellent treatment, any one side thereof. In the electrode for a fuel cell 300, the gas diffusion layer 220 and the catalyst layer 230 are integrated to the nanofiber web 310. The present invention provides a electrode for a fuel cell which is effective in reducing the production cost of the fuel cell, compacting the fuel cell, and improving the efficiency in generating power, and a method for producing the same.
