<P>PROBLEM TO BE SOLVED: To provide a compound electrolyte membrane for a fuel cell which is suitable as a base material for an electrolyte membrane for solid polymer fuel cell and satisfies both of a mechanical strength and power generation characteristics while maintaining a reinforcing membrane in a certain weight. <P>SOLUTION: The compound electrolyte membrane for fuel cell is manufactured by including a first process in which the thickness (d) of the reinforcing membrane is formed thinly so as to be d/D=0.1 to 0.3 against the thickness (D) of the compound electrolyte membrane and a second process in which the reinforcing membrane obtained in the first process is compounded with a polymer electrolyte membrane, thereby, the compound electrolyte membrane for fuel cell has the reinforcing membrane of a certain weight in the polymer electrolyte membrane, and the thickness (d) of reinforcing membrane / the thickness (D) of compound electrolyte membrane=0.1 to 0.3. <P>COPYRIGHT: (C)2010,JPO&INPIT |
