Highly proton conducting organic‐inorganic glass hybrids were prepared using the sol‐gel method, the electrical conductivities of which were studied in relation to their thermal and mechanical properties. The solution of hydrolyzed Si(OC 2 H 5 ) 4 and H 3 PO 4 was reacted with a perfluorosulfonic polymer such as Nafion, forming a homogeneous hybrid‐gel. The conductivity of the hybrid‐gel incorporated with 20 % Nafion is ∼10 mS/cm at room temperature, which increases as the treatment temperature increases and reaches ∼ 60 mS/cm at 200 °C. The hybrid continues to exhibit high conductivity after heating to 250 °C and improved mechanical property over the inorganic glass.
