Novel composite electrolytes based on phosphate and oxide matrix were investigated for intermediate fuel cells operative at 200-300°C, and the promotional effect of the hetero-interface between the conductive phase and matrix was examined. Interfacial conductive phase was formed between phosphate and SiO2 treated with phosphoric acid, leading to an increase in the conductivity. CsH5(PO4)2/SiO2 composite membrane employing silica fiber membrane as a matrix with a thickness of 70 and 150 μm was fabricated and applied to an electrolyte for an intermediate-temperature fuel cell, which demonstrated good performance of 105 mW cm-2 at 200°C due to a low area specific resistance of 0.32 Ω cm2, and was stable at 200°C under a constant current load of 100 mA cm-2 for 50 h.

研究了基于磷酸盐和氧化物基质的新型复合电解质，用于在200-300°C下运行的中间燃料电池，并检查了导电相和基质之间杂音界面的促进作用。用磷酸处理的磷酸盐和SIO2之间形成界面导电相，导致电导率增加。制造了使用硅纤维膜的CSH5（PO4）2/SIO2复合膜，厚度为70和150μm，并应用于电解质中，用于在2005°C的2005 MW CM-2的良好性能下，由于0.322222222222222222222222222222222222222222222222222222222 cm 2 100 mA cm-2持续50 h。
