<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a catalyst paste for fuel cell in which the particle size of a catalyst carrier is made small. <P>SOLUTION: The method for manufacturing the catalyst paste for fuel cell implements a process in which a catalyst carrier which is carried in a conductive substance having a nature in which a catalyst is coagulated, a proton conduction substance, a dispersion medium, and a media-less mixer 1 which disperses and kneads without using a medium for dispersion kneading are prepared and a process in which in the state that an admixture mixing the catalyst carrier, the proton conduction substance, and the dispersion medium is formed, the catalyst carrier is dispersion kneaded by the media-less mixer 1 with a pulverization energy in which the total sum of the pulverization energy is 4.0-25.0 [J/cc]. <P>COPYRIGHT: (C)2009,JPO&INPIT |
