Abstract

An inorganic proton exchange membrane based on sintered mesoporous silica and phosphoric acid was developed with a high proton conductivity of 0.06 S cm−1 at 200 °C, achieving an excellent power output of 689 mW cm−2 in H2 at 190 °C and 200 mW cm−2 in methanol at 200 °C with no external humidification.
