ORGANIC-INORGANIC HYBRID ELECTROLYTE MEMBRANE, METHOD FOR FABRICATING THE SAME AND FUEL CELL

摘要

PURPOSE: An organic-inorganic hybrid electrolyte membrane is provided to prevent the leakage of inorganic particles in the operation of a fuel cell, to effectively reduce fuel penetration, to improve ion conductivity and to maintain excellent performance in a high temperature/low humidification condition. CONSTITUTION: An organic-inorganic hybrid electrolyte membrane comprises: a polymer(12) having an ion exchange group(10) and inorganic particles(16) which are chemically bonded with the polymer and have the ion exchange group. A method for preparing the organic-inorganic hybrid electrolyte membrane comprises the steps of: preparing an organic membrane containing the polymer having the ion exchange group; absorbing an inorganic particle precursor having the ion exchange group to the organic membrane; and bonding a polymer(14) having the ion exchange group with the inorganic particle precursor having the ion exchange group using a sol-gel reaction, and inorganic particle precursors having the ion exchange group.
