発明の名称 (英語) PRODUCTION METHOD FOR FINE METAL PARTICLES, PRODUCTION METHOD FOR FUEL CELL ELECTRODE CATALYST, SUPPORTED FINE METAL PARTICLE CATALYST, AND FUEL CELL ELECTRODE CATALYST
発明の概要(英語) Provided is a method for efficiently producing fine metal particles that can be used as a fuel cell electrode catalyst. The production method for fine metal particles according to the present invention is provided with a hydrogen bubbling step in which bubbling of a reaction gas containing hydrogen gas is performed in a reaction solution in which fine metal particles in a dispersed state and a water-soluble precious metal precursor coexist in a water-containing solvent.
