RESEARCH RESULTSThe fuel cell has great possibilities. We use proton conductive glasses as a solid electrolyte, and are developing fuel cell with all solid electrolyte working at the intermediate temperature (150〜400℃) from this point of view. Furthermore, the research and development of these glasses are performing for the purpose of the application to a hydrogen shade battery and EC devices. In this work, we describe synthesis, conductivity of the glasses, chemical resistance and physical propertiesPredetermined quantity of source materials were mixed in a ball mill for one hour. The mixture was heated in the electric furnace at 600〜800℃, for 30 min. then, thermal product was poured into a mold and cooled from 300℃ to room temperature to prepare a glass samples. These samples were poured into a melting pot and inserted this in the electric furnace that setting was settled and heated.IR spectra indicated that the big absorption was observed in 2800cm^<-1> which was absorption O-H band. The content of mobile proton in glass can calculate identified from the relation of absorbance and film thickness of this absorption band. The electric conductivity of these samples showed 3.99×10^<-4>S・cm^<-1> and 7.61×10^<-6>S・cm^<-1> at 200℃ and room temperature. It is thought that glass of this system has high proton conductivity when compare it with a melt quenching method.

研究结果燃料电池有很大的可能性。我们采用质子导电玻璃作为固体电解质，从这个角度出发，正在开发全固体电解质工作在中间温度（150 ~ 400℃）的燃料电池。此外，这些玻璃的研究和开发是为了应用于氢遮阳电池和EC设备。在这项工作中，我们描述了玻璃的合成，电导率，耐化学性和物理性能。预定数量的原料在球磨机中混合一小时。将混合物在电炉中600 ~ 800℃加热30 min，然后将热产物倒入模具中，从300℃冷却至室温，制成玻璃样品。这些样品被倒入一个熔炉中，并将其插入电炉，使其凝固并加热。红外光谱表明，在2800cm^<-1>为吸收O-H波段有较大的吸收。根据吸收带的吸光度与膜厚的关系，可以计算出玻璃中可移动质子的含量。在200℃和室温下，样品的电导率分别为3.99×10^<-4>S·cm^<-1>和7.61×10^<-6>S·cm^<-1>。与熔融淬火法相比，该体系的玻璃具有较高的质子导电性。
