<p><P>PROBLEM TO BE SOLVED: To provide a polyelectrolyte film which has little swelling by water, methanol, etc. and a method of manufacturing the same and to provide a film-electrode connector for a fuel cell showing good fuel cell characteristics and the fuel cell. <P>SOLUTION: The polyelectrolyte film is formed by filling up an electrolyte polymer with the state of a polymer in pores of a polyimide porous membrane, and has a proton conductivity with 60°C, a relative humidity of 95% of 4.0×10<SP>-2</SP>S/cm to 1.0 S/cm. The method of manufacturing the polyelectrolyte includes a step of immersing the polyimide porous membrane into the liquid-like article of the electrolyte polymer having a proton conduction function, a step of performing a pressure reducing operation in the immersed state, and a step of filling up the electrolyte polymer into the pores of the polyimide porous membrane. The film-electrode connector, a solid polymer type fuel cell and a direct methanol type fuel cell each uses the polyelectrolyte film. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
