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.
