POLYMER ELECTROLYTE MEMBRANE, METHOD FOR PRODUCING THE SAME, AND PROTON CONDUCTIVITY EVALUATION METHOD FOR POLYMER ELECTROLYTE MEMBRANE |
摘要 |
The present invention provides a polymer electrolyte membrane with excellent proton conductivity in its thickness direction. Preferably, the polymer electrolyte membrane contains a polymer compound comprising an ionic segment having an ionic functional group and a nonionic segment having substantially no ionic functional group, and the phase containing ionic segments as a main component and the phase containing nonionic segments as a main component are phase-separated, and in the surface region thereof, the change in the amount of the ionic segment from the surface toward the interior substantially decreases monotonically.
