中文摘要：

以H2S作为燃气，采用燃料电池技术脱除H2S，并同时得到电能和其他环境友好共生副产物，这是一种理想的酸性废气资源化手段。而燃料电池电输出性能大小与固体电解质材料有关。采用尿素燃烧法制备Zr掺杂的SiCeO3钙钛矿型质子固体电解质。电解质前驱体粉末经873K煅烧后具有典型的钙钛矿结构。在773-1273K温度范围内，固体电解质Zr掺杂的SrCeO3具有较高的体电导率，其值在10^-2S·cm^-1左右。将Zr掺杂的SrCeO3电解质构成结构为MoS2-SCZY-Ag的单体SOFC，获得了开路电压值为0．70V和最大的电功率密度1．22mW·cm^-2。这将为天然气、化肥等工业产生的H2S废气提供一种可资源化利用途径。

英文摘要：

H2S is a corrosive, noxious gaseous pollutant, and the fuel cell technology is considered to be an environmental/energy means for desulfurization, utilizing H2S as fuel to produce electricity and other cogeneration byproduct. Urea combustion method was adopted to prepare SrCeO3 doped with Zr, proton conductor with perovskite structure. The precursor powder has typically perovskite structure after being calcined at 873 K, and the particle size is 30 ~ 40 nm. In 773-1273 K, SCZY has highly dense microstmcture and the conductivity approaches 10^-2 S·cm^-1. In the single fuel cell composed of MoS2-SCZY-Ag, the open circuit voltage is 0.7 V, the max power density is 1.22 mW·cm^-2. The new technology will provide us with the way to recycle the waste gas, H2S, produced by chemical industry or nature gas industry.
