摘要： The present invention relates to a preparing process an organic-inorganic composite polymer membrane for fuel cell by using sol-gel process. At this time, it is characterized in that when a sulfonated hydrocarbons polymer having ion conductivity is cast with film shape, sol-gel process which enables to distribute an inorganic matter having an excellent cation exchange and moisture holding capacity homogeneously is used. With homogeneous introduction of an inorganic matter into a polymer matrix by sol-gel process according to the present invention, it is possible to improve a phenomenon that an inorganic matter is partially concentrated at some position, thereby enabling to obtain an ion conducting organic-inorganic composite polymer membrane having an excellent ion conductivity.
