摘 要与固体氧化物燃料电池（SOFC）相比，质子导体燃料电池（PCFC）具有更低的活化能和质子传导率， 如果电池制备工艺和阴极匹配问题得到解决， 那么在氢气和烃类气氛中，质子导体燃料电池（PCFC）的导电性能比固体氧化物燃料电池（SOFC）更加优越。不仅如此，质子导体燃料电池的工作温度（350～600℃）比固体氧化物燃料电池的工作温度（700～1000℃）低，可以降低对硬件设备的要求。在目前质子导体燃料电池的研究中，以铈酸钡基为电解质的质子导体固体氧化物燃料电池尤为受到关注。BaCeO3基的质子导体具有较高的电导率，目前 Gd3+掺杂BaCeO3是迄今为止报道最高的质子传导材料，成为SOFC 电解质的研究热点。本实验中除了在铈酸钡中掺杂Gd3+外，还在其中加入 In3+，这是因为 In3+可以大幅提高铈酸钡材料的化学稳定性和烧结活性，并在其中加入 ZnO 以降低其反应烧结温度。选取了传统Ni 基作为阳极，选取了一种最新报道的具有钙钛矿结构的 BaCo0.4Fe0.4Zr0.1Y0.1O3-δ(BCFZY0.1)作为阴极，采用单步烧结法在中温下，制备出具有具有三明治结构的Ni 基/BCIGO721/BCFZY0.1 电池。本论文的工作分为三个部分，第一部分是制备了前期电池结构所需粉体，采用了反应烧结法制备了BCIGO721 电解质材料，用氨水共沉淀法制备了 NiO 及混合BCIGO721 粉末压片作为阳极基底，用溶胶凝胶法制备阴极材料 BaCo0.4Fe0.4Zr0.1Y0.1O3-δ(BCFZY0.1)，经过 XRD 和 SEM 测试，可分析出这三种材料是可以作为电池的结构；第二部分是制备单电池结构，使用共压法在直接制成具有三明治结构的燃料电池生坯，经过烧结和浸渍得到完整的质子导体燃料电池，并通过 XRD 及 SEM 来观察电池的结构和物相；第三部分是封装电池，依据电池的测试结果对电池设计方案进行改进。58194

Abstract Compare with the solid oxide fuel cell (SOFC), Proton conductors fuel cell (PCFC)has lower activation energy and proton conductivity of preparation process and if thebattery cathode matching problem is solved, so in an atmosphere of hydrogen and hydrocarbon, Proton conductors fuel cell (PCFC) conducts electricity better than solid oxide fuel cell (SOFC) is superior. Not only that, the fuel cell of Proton conductor operating temperature (350~600℃) than the working temperature of the solid oxide fuel cell (700~1000℃), can reduce the requirement for hardware devices. Many fuel cell of Proton conductor, cerium and barium base for solid oxide fuel cell electrolyte Proton conductors are particularly concerned. BaCeO3 has a higher electrical conductivity of Proton conductr, currently Gd3+ doped BaCeO3 is by far the highest reported of Proton conducting materials, become a hot spot in SOFC electrolyte. This experiment in addition to outside the barium cerium-doped Gd3+, also added In3+, this is because the In3+ can significantly improve cerium and barium chemical stability and sintering activity and adding ZnO to lower the reaction temperature. Selected traditional Ni based as the anode, a selection of the latest reported BaCo0.4Fe0.4Zr0.1Y0.1O3 with perovskite structure (BCFZY0.1) as a cathode, sintering temperature in a single step, preparation of Ni-base/BCIGO721/BCFZY0.1 battery with a sandwich structure.This thesis is pided into three parts, the first part is the preparation needed for thecell structure in the early powder, were prepared by reaction sintering of BCIGO721 electrolytes, ammonia was prepared by coprecipitation NiO and mixed BCIGO721 pressed powder as an anode substrate cathode materials prepared by sol-gel BaCo0.4Fe0.4Zr0.1Y0.1O3-δ (BCFZY0.1), by XRD and SEM tests can analysis out this threespecies material is can as battery of structure; second part is preparation single battery structure, using total pressure method in directly made has sandwich structure of fuel battery health billet, after sintering and impregnated get full of Proton conductor fuel battery, and through XRD and the SEM to observation battery of structure and real phase; third part is package battery for test, according to the result of test，we will adjust the parts of the cell.
