摘要： PROBLEM TO BE SOLVED: To provide electrode catalyst for a fuel cell which forms a catalyst layer without disturbing diffusion of gas while having a sufficient catalyst amount. SOLUTION: This electrode catalyst for a fuel cell is prepared by supporting platinum particles to carbon, and is characterized in that the average particle diameter of the platinum particles is 1.9-2.3 nm; and when it is assumed that the electrode catalyst for a fuel cell is 100 wt.%, the platinum particles is 60-80 wt.%. This manufacturing method is characterized by having a dispersion solution adjustment process, a buffering agent addition process, and a reduction-deposition process. The electrode catalyst for a fuel cell has an effect to provide electrode catalyst for a fuel cell for forming a catalyst layer without disturbing dispersion of gas while securing a sufficient catalyst amount (platinum particle amount) because a large quantity of the platinum particles each having a small particle diameter are supported by carbon.
