<p><P>PROBLEM TO BE SOLVED: To provide a composite sheet for direct methanol fuel cells, which is excellent in methanol diffusivity and which can supply methanol to a large area of an anode by diffusion pass-through effect even if an area of a methanol solution delivery portion of a fuel cartridge is comparatively small. <P>SOLUTION: The composite sheet for direct methanol fuel cells includes a polyphenylene sulfide-based resin layer and a cellulose fiber layer continuously formed on at least one principal surface of the polyphenylene sulfide-based resin layer, wherein the content of the polyphenylene sulfide-based resin is 10 to 45 wt.%, and the total thickness is 0.05 to 0.2 mm. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
