Abstract
A polymer electrolyte membrane having good resistance to radicals is provided. A polymer electrolyte membrane is characterized of containing organic/inorganic hybrid particles in which a surface of an inorganic particle, which is a radical scavenger, is modified with organic compounds in a polymer electrolyte. As the organic/inorganic hybrid particles in which a surface of an inorganic particle is modified with organic compounds, a radical scavenger prepared by reacting inorganic particles with organic compounds in a solvent by supercritical or subcritical hydrothermal synthesis is preferred.
Claims6
A polymer electrolyte membrane containing, in a polymer electrolyte, organic/inorganic hybrid particles in which a surface of an inorganic particle, which is a radical scavenger, is modified with one or more organic compounds selected from C3-20 fluorocarbon-based carboxylic acid.
