A Novel Water‐Free Proton‐Conducting Solid Electrolyte based on an Organic/Inorganic Hybrid

A novel water-free proton-conducting solid electrolyte based on an organic (CImSS)/inorganic (silicate) hybrid is presented (see Figure). In the absence of water, a remarkably high proton conductivity of around 10–4 S cm–1 at 160 °C is obtained for the CImSS/MTEOS-based silicate hybrid, which may be attributed to the well-developed percolation of the proton-conducting phase (CImSS) and its weaker interaction with the silicate.
