Description

本発明は、固体高分子電解質膜の両方の面に触媒層が設けられた燃料電池用膜・触媒層構造体の製造方法に関するものである。この製造方法では、転写用基材に触媒層を塗布する工程を有している。さらに、触媒層が塗布された転写用基材を、乾燥処理用台部材上に載置するとともに、前記触媒層の外周部位を該触媒層の中央部位よりも下方に配置した状態で、乾燥処理を行う工程を有している。そして、乾燥処理が終了した後、固体高分子電解質膜の少なくとも一方の面に、転写用基材から触媒層を転写する工程を有している。 The present invention relates to a method for producing a membrane / catalyst layer structure for a fuel cell in which catalyst layers are provided on both sides of a solid polymer electrolyte membrane. This manufacturing method includes a step of applying a catalyst layer to a transfer substrate. Further, the transfer substrate coated with the catalyst layer is placed on the drying treatment table member, and the drying process is performed with the outer peripheral part of the catalyst layer being disposed below the central part of the catalyst layer. The process which performs is performed. After the drying process has been completed, at least one surface of the solid polymer electrolyte membrane, and has a step of transferring the catalyst layer from the transcription substrate for.
