Method for depositing catalyst in fuel cell, fuel cell manufactured by the same and operation apparatus for the same

Abstract

Provided are a method for depositing a catalyst in a fuel cell, a fuel cell obtained by the method, and an apparatus for operating the fuel cell. The method for depositing a catalyst in a fuel cell includes: oxidizing a catalyst provided at the top of the cathode with air introduced to the cathode under the operating condition of the fuel cell; and depositing the oxidized catalyst gas at the reactive zone of the cathode. The method allows deposition of an activated catalyst ingredient at the cathode of a fuel cell by disposing a catalyst (such as Pt, Ag, Pd, Ru, etc.) highly reactive to reduction of oxygen at the side to which oxygen is introduced, and oxidizing and vaporizing the catalyst under an actual operating condition.
