Abstract

H2/O2 fuel cells equipped with proton-conducting Nafion®/phosphosilicate (NPS) glass membranes, which are prepared from phosphosilicate glass and a perfluorosulfonic acid polymer, are characterized, and their performances are improved step by step by using Nafion® resin as an adhesive, increasing operation temperature, adopting a thin-film pressure sensor, and reducing glass membrane thickness. Finally, the fuel cell with a 500μm thick NPS glass membrane releases a peak power density of 207mWcm−2 at 70°C.
