<P>PROBLEM TO BE SOLVED: To provide a transfer sheet for easily manufacturing a catalyst layer-electrolyte membrane laminate, and a catalyst layer-forming paste composition for manufacturing the transfer sheet. <P>SOLUTION: The catalyst layer-forming paste composition is obtained by mixing a hydrogen ion conductive polymer electrolyte and an organic solvent in an aqueous dispersion of a catalyst-carrying carbon particle. In the paste composition, (1) the organic solvent has a solubility parameter of 9 to 12 and a boiling point of 60 to 150°C, (2) the organic solvent comprises at least one selected from the group consisting of 1-propanol, 2-propanol and t-butanol, and 1-butanol, and (3) the composition does not contain polyalcohol. <P>COPYRIGHT: (C)2012,JPO&INPIT |
