METHOD FOR PREPARING FUEL CELL ELECTRODE, AND METHOD FOR PREPARING MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL CONTAINING THE SAME

摘要

Provided are a method for preparing an electrode for a fuel cell and a method for preparing a membrane-electrode assembly for a fuel cell containing the same. The electrode for the fuel cell can be prepared by polarizing some of the upper parts of a porous conductive film and introducing a catalyst layer on the porous conductive film where some of the upper part is modified. Accordingly, a first catalyst can be uniformly spread on the polarized portion of the porous conductive film. As a result, the effective surface area of the catalyst is increased, so the catalyst amount used can be reduced. Additionally, even if density of the porous conductive film is increased, the catalyst can be easily introduced inside the porous conductive film.
