COMPOSITE POWDER, METHOD FOR MANUFACTURING COMPOSITE POWDER, GAS DIFFUSION LAYER, MEMBRANE ELECTRODE ASSEMBLY, AND FUEL CELL

A method for manufacturing a composite powder, the method includes: stirring and mixing a polymer resin and at least one or more of fibers and particles with a dispersion solvent to obtain a mixed solution of the polymer resin and at least one or more of the fibers and the particles; spraying the mixed solution in a form of droplets into a chamber whose inside is cooled to a temperature lower than a melting point of the dispersion solvent to obtain a frozen composite powder in which the droplets are frozen; and sublimating the dispersion solvent contained in the frozen composite powder to obtain a dried composite powder.
