FUEL CELL ELECTRODE BEING UNIFIED CATALYST LAYER AND GAS DIFFUSION LAYER WITH CARBON NANOFIBERS WEB AND METHOD OF PREPARING THE SAME AND FUEL CELL USING THE SAME

摘要

PURPOSE: A fuel cell electrode is provided to minimize thickness using a carbonized or graphitized nanofiber web, to ensure excellent mechanical and electrical properties, and to improve compaction and improvement of generation efficiency for a fuel cell. CONSTITUTION: A fuel cell electrode in which a gas diffusion layer(220) and a catalyst layer(230) are integrally formed using one sheet of nanofiber web(300) comprises carbonized or graphitized nanofiber web of which one side or whole is water-repellent; and a catalyst layer formed by fixing a platinum-based catalyst(320) at one side when whole is water-repellent or at the other side when one side is water-repellent.
