<P>PROBLEM TO BE SOLVED: To provide a moisture control sheet which can be used for manufacturing a fuel cell having excellent power generation performance as a result of exhibiting excellent balance of gas diffusibility, drainage and moisture retention even under low humidification condition. <P>SOLUTION: The moisture control sheet is a self-supporting moisture control sheet that is used while interposed between the catalyst layer and the gas diffusion layer of a solid polymer fuel cell. The moisture control sheet is produced by filling a non-carbonated porous base material sheet, which is not carbonated after formation of a porous base material sheet, with a fluorine-based resin and/or a conductive agent and has a degree of air permeability resistance in the range of 200-750 sec/100 mL. Inventive gas diffusion sheet, membrane-electrode assembly, and solid polymer fuel cell are equipped with the moisture control sheet. <P>COPYRIGHT: (C)2012,JPO&INPIT |
