Preparation method for improving stability of proton conductor electrolyte in carbon dioxide
The invention discloses a preparation method for improving the stability of a proton conductor electrolyte in carbon dioxide, and relates to the technical field of solid oxide batteries and solid oxide electrolytic cells. And preparing a nano-structure additive of alkaline earth metal oxide, transition metal oxide or VA main group metal oxide by adopting a vacuum impregnation method to obtain the alkaline proton conductor electrolyte of which the surface is modified with the additive. The alkaline proton conductor electrolyte of which the surface is modified with the nano-structure additive is applied to a proton type hydrocarbon ceramic membrane fuel cell or high-temperature electrolysis of carbon dioxide, so that the stability of the electrolyte can be effectively enhanced and the ohmic loss can be reduced; therefore, the performance and the stability of the solid oxide fuel cell and the electrolytic tank in the carbon dioxide atmosphere are greatly improved.
本发明公开了一种提高质子导体电解质在二氧化碳中稳定性的制备方法，涉及固体氧化物电池和固体氧化物电解池技术领域，通过纳米添加剂表面修饰法，在固相反应法获取的铈酸钡和锆酸钡系列电解质表面，采用真空浸渍法制备碱土金属氧化物、或过渡金属氧化物、或VA主族金属氧化物的纳米结构添加剂，得到表面修饰添加剂的碱性质子导体电解质。本发明将得到的表面修饰纳米结构添加剂的碱性质子导体电解质应用到质子型碳氢陶瓷膜燃料电池或高温电解二氧化碳，可以有效增强电解质的稳定性及降低欧姆损失，由此大大提高固体氧化物燃料电池和电解池在二氧化碳气氛下的性能和稳定性。
