Abstract

An organic–inorganic hybrid ionic conductive material was prepared through oxidation of thiol groups in a surface‐modified porous glass. Surface‐modified pores in the hybrid materials acted as permeation paths for protons. Proton conductivity of the hybrid material was 4.2 × 10 −2 S/cm at 120°C under 100% relative humidity. This hybrid material was thermally stable at high temperature (above 100°C) due to the temperature‐tolerant inorganic frameworks.
