【摘要】 通过变换工作温度、施加电压、氢气分压、氢气流速等参数，对致密材料ＳｒＣｅ０．９５Ｙ０．０５Ｏ３－δ的电化学特性做了研究．同时，对该材料在高温下的电导稳定性做了初步探索．发现该种材料在高温氢气氛中有较好的质子传导性，施加电压及氢分压改变对质子传导性影响显著，流速对之影响在低温区不明显，但在高温区影响较大．最佳流速可选为 ３０ｍＬ／ｍｉｎ．更多还原

【Abstract】 Parameters such as applied voltage, hydrogen partial pressure, flow rate were changed respectively in order to research the electrochemical properties of dense SrCe0.95Y0.05O3-δ Meanwhile, the stability of this material was investigated. It suggests that this dense material exhibits excellent proton conduction at high temperature in atmosphere contained hydrogen. Both the applied voltage and hydrogen partial pressure contribute mostly to proton conduction. The proton conduction is attributed to flow rate of hydrogen less at low temperature while more at high temperature. The optimistic flow rate is 30mL/min.更多还原
