More particularly, the present invention relates to a metal catalyst for a fuel cell, which comprises a carbon-based catalyst carrier, a chelating agent, and a first solvent, which are mixed with a reducing agent to effect a primary reduction, ; Mixing a transition metal precursor with a second solvent to form a transition metal precursor mixture; Dispersing the carbonaceous catalyst carrier doped with the chelating agent into the transition metal precursor mixture, and adding a reducing agent to the metal catalyst to form a metal catalyst, thereby forming a metal catalyst. According to the present invention, it is possible to improve the electrochemical efficiency of a metal catalyst and to maximize efficiency in production, while reducing the content of platinum, thereby contributing to the production of an economical fuel cell. do. |
