ELECTRODE CATALYST FOR FUEL CELL AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an electrode catalyst for a fuel cell and manufacturing method thereof capable of obtaining a fuel cell high in generation efficiency, generation power, and reliability.

SOLUTION: The electrode catalyst for a fuel cell is provided in which flake grains detached from lepidocrocite-type titanate (CsxTi2-x/4O4(0.5≥x≥1)), which is laminar titanium oxide and catalyst particles containing noble metal are supported on carbon carrier. The manufacturing method includes the steps of: obtaining flake grain support carbon carrier; and supporting the catalyst particles on the flake grain support carbon carrier. The manufacturing method includes the steps of: obtaining catalyst particle support carbon carrier; and supporting the flake grains on the catalyst particle support carbon carrier. The manufacturing method includes the steps of: obtaining catalyst particle support flake grains; and supporting the catalyst particle support flake grains on the carbon carrier.
