Proton-conducting glass films...

Highly proton-conducting glass films have been prepared by controlling the pore size of the silica film. The conductivity of films with pores perpendicular to the substrate surface was high, whereby the conductivity increased with increasing water content. The high conductivity was retained at relatively low humidity due to the restriction of water movement in the pores. These porous proton-conducting materials attract considerable interest for use in small fuel cell systems (M. Nogami et al., June 18, Adv. Mater. 2002, 14, 911-913).
