本文介绍了一种基于无机玻璃膜的燃料电池电解质，它具有高质子传导性。所用的二元玻璃（P2 O 5-SiO2）-通过PO（CH 3）3与水解的Si（OC 2 H5）4反应制备-被证明不仅可用作氢燃料电池中的质子导体，而且可用作氢气传感器。由于P2 O 5-SiO2具有良好的化学稳定性和在H2-O2燃料电池中的应用前景，因此P2 O 5-SiO2有望取代全氟离聚物作为H2-O2燃料电池的电解质。
A fuel cell electrolyte based on an inorganic glass membranewith a high proton conductivity is described by these authors. The binary glass used (P2O5–SiO2)—prepared by reacting PO(CH3)3with hydrolyzed Si(OC2H5)4—is demonstrated to not only be useful as a proton conductor in hydrogen fuel cells but also as a hydrogen gas sensor. Because of its good chemical stability and promising performance in H2–O2fuel cells it is believed that P2O5–SiO2could replace perfluorinated ionomers as the electrolyte in these cells.
