Abstract
A catalyst ink for improving the performance of catalyst electrodes in a fuel cell is produced by the following procedure. A catalyst dispersion is prepared by dispersing catalyst-supported particles as conductive particles with a catalyst supported thereon in a solvent. A gel material having viscoelasticity is prepared by mixing an ionomer with a volatile solvent. A catalyst ink having a desired viscosity is produced by stirring and mixing the catalyst dispersion with the gel material.
