The proposed research is concerned with the use of low temperature solid electrolytes in fuel cells. The proposed research addresses the material requirements for low electronic and high ionic conductivity. The proposed approach is the formation of a two layer composite electrolyte. The first layer will be a CeO2 -based or perovskite-based solid electrolyte with high ionic conductivity upon which a thin layer of zirconia is deposited, using electrochemical vapor deposition, to block the electronic current.

拟议的研究与燃料电池中低温固体电解质的使用有关。拟议的研究解决了低电子电导率和高离子电导率的材料要求。提出的方法是形成两层复合电解质。第一层将是具有高离子电导率的基于CEO2的或基于钙钛矿的固体电解质，并使用电化学蒸气沉积沉积一层薄层的氧化锆层以阻断电子电流。
