<P>PROBLEM TO BE SOLVED: To provide a catalyst layer transfer sheet for manufacturing a catalyst layer/electrolyte film junction body endowed with both excellent hydrophilicity and water repellency. <P>SOLUTION: The catalyst layer transfer sheet has a permeating layer 2 for gas and liquid formed on one of the surfaces of a base material sheet, and a platinum-containing catalyst layer 5 formed on the permeating layer. The permeating layer 2 has a hydrophilic region 3 and a water-repellent region 4. By transferring the catalyst layer of the transfer sheet to the solid electrolyte film with the use of the catalyst layer transfer sheet, a catalyst layer/electrolyte film junction body having both excellent hydrophilicity and water repellency is manufactured. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
