Abstract
Provided are a method for preparing a catalyst layer by an in-situ sol-gel reaction of tetraethoxysilane, and a fuel cell including the catalyst layer prepared thereby. Addition of silica mitigates specific adsorption of sulfonate groups contained in a Nafion ionomer on a Pt catalyst layer in a high-voltage region where the role of a catalyst predominates, resulting in improvement of ORR performance.
