  • POLYMER ELECTROLYTE-CATALYST COMPOSITE STRUCTURE PARTICLE AND MANUFACTURING METHOD THEREOF, ELECTRODE, MEMBRANE ELECTRODE ASSEMBLY (MEA), AND ELECTROCHEMICAL DEVICE
    Publication number: 20120064431
    Abstract: Polymer electrolyte-catalyst particles that are effective in preventing agglomeration of catalyst particles and polymer electrolyte particles, effective in the formation of ion pathways by polymer electrolyte particles and electron pathways by catalyst particles, and that are able to realize strong catalytic performance by improving the use efficiency of the catalyst particles and a manufacturing method thereof, electrodes formed using such composite structure particles, a membrane electrode assembly (MEA), and an electrochemical device are provided. First, the dispersion liquid in which an ion conducting polymer electrolyte material is dispersed and microparticles 1 are mixed, and the surfaces of the microparticles 1 are coated by an ion conducting polymer electrolyte layer 2 that does not contain a catalyst material.
