We prepared a TiO2-P2O5 self-ordered, crystalline glass, mesoporous nanocomposite (CGMN) with water-holding capacity at an intermediate temperature region (130-200 °C). This TiO2-P2O5 CGMN showed the high proton conductivity of 2 × 10-2 S cm-1 at 160 °C under fully saturated humidification conditions (100% RH). Additionally, these conductivities were stable at intermediate temperature conditions. The TiO2-P2O5 CGMN may have a potential not only for the fuel cell electrolytes operated at intermediate temperature conditions but also for electrochemical devices, including electrochromic displays, chemical sensors, lithium rechargeable batteries, and others.
