<P>PROBLEM TO BE SOLVED: To provide a layer built fuel cell wherein permeation of an electrolyte solution into an electrode layer is sufficiently suppressed while forming a solid polymer electrolyte layer by applying it on the electrode layer, and output can be heightened as a result, and to provide its manufacturing method. <P>SOLUTION: The air permeation flow rate of an electrode with a catalyst is adjusted within a range of 10,000-12,000 ml*mm/cm<SP>2</SP>/min. Therefore, when providing an electrolyte membrane 12 by applying an electrolyte solution on it, since permeation of the electrolyte solution into the catalyst layer 28 is suitably suppressed, it is suitably suppressed that gas diffusion performance of the catalyst layer 28 and the electrode 30 is deteriorated by the penetrated electrolyte or their reactivity with the catalyst is deteriorated. Thereby, this layer built fuel cell having high output can be obtained. <P>COPYRIGHT: (C)2008,JPO&INPIT |
