We constructed a fuel cell using a proton-conducting porous silica film with thickness of 650 nm. This fuel cell delivered an open circuit voltage (OCV) of 540 mV and a maximum power density of 51 μW/cm2 at room temperature. The silanol group on the pore wall promoted proton conduction, and water molecules adsorbed in the pore suppressed permeation of fuel gas.
