PROBLEM TO BE SOLVED: To provide a moisture control sheet which is superior in moisture retention in addition to drainage, gas diffusibility and handleability, and a gas diffusion sheet, a film-electrode assembly, and a solid polymer fuel battery which are arranged by use of the moisture control sheet.SOLUTION: The moisture control sheet is independent and in use, is disposed adjacently to a catalyst layer of a solid polymer fuel battery. The moisture control sheet comprises: a nonwoven fabric layer including conductive fiber including a hydrophobic organic resin and conductive particles at least inside the hydrophobic organic resin; and a fiber layer including a hydrophilic fiber. The gas diffusion sheet, the film-electrode assembly and the solid polymer fuel battery all comprise the moisture control sheet. |
