<P>PROBLEM TO BE SOLVED: To provide a new catalyst layer-electrolyte membrane laminate of a solid polymer fuel cell in which a hydrophilic group is sufficiently formed, in which flooding or dry-up can be prevented, and in which battery characteristics are improvable, and provide its manufacturing method. <P>SOLUTION: The catalyst layer-electrolyte membrane laminate is the catalyst layer-electrode membrane laminate for the solid polymer type fuel cell, wherein the catalyst layer is laminated on one face of the electrolyte membrane, and the hydrophilic group is given to a catalyst layer surface contacted with the electrolyte membrane by an atmospheric pressure plasma method. This catalyst layer-electrolyte membrane laminate is manufactured by the manufacturing method provided with a first process of carrying out a treatment on a catalyst layer transfer sheet in the presence of steam by the atmospheric pressure plasma method, and a second process of heat pressing the catalyst layer transfer sheet obtained in the first process onto one face or both faces of the electrolyte membrane. <P>COPYRIGHT: (C)2007,JPO&INPIT |
