尽管质子导电固体氧化物燃料电池(PCFC)优于传统燃料电池，但制约其实验研究和商业化应用的两个主要挑战是制造成本高和难以规模化。此外，水基流延技术作为一种新的制备方法，在制备薄薄、大规模、低成本、环境友好的电解液层方面得到了广泛的应用。本文将多层水基流延和共烧技术相结合，制备了80 mm×80 mm阳极型质子传导固体氧化物燃料电池。其晶体结构为NiO-BaZr0.1Ce0.7Y0.1Yb0.1O3-Delta(BZCYYb)/BZCYYb(约12微米)/La0.6Sr0.4Co0.2Fe0.8O3-Delta(LSCF)-BZCYYb。在以3%的加湿氢气为燃料、常压空气为氧化剂的条件下，800℃时电池性能达到389 mW cm(-2)，微观结构均匀。结合以往工作的成功经验，本工作可为今后大规模PCFC的组装提供理论和统计上的积累和参考。
Although proton-conducting solid oxide fuel cells (PCFCs) is superior to traditional fuel cells,the two main challenges for restricting the experimental research and the commercialization of PCFCs application are its high manufacturing cost and difficulty in scale-up. In addition, the aqueous-based tape casting process as a novel strategy has been widely applied in fabricating thin, large-scale, cost-effective and environment-friendly electrolyte layer. In this paper, an 80 mm x 80 mm anode-supported proton-conducting solid oxide fuel cell is obtained through combining the multi-layer aqueous-based tape casting and co-sintering technology. The configuration of PCFCs is NiO-BaZr0.1Ce0.7Y0.1Yb0.1O3-delta (BZCYYb)/BZCYYb (similar to 12 mu m)/La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF)-BZCYYb. The performance of the cell with homogeneous microstructure reaches 389 mW cm(-2) at 800 degrees C in condition of 3% humidified hydrogen as fuel and normal air as oxidant. Combined with the successful experience of previous work, this work can provide theoretical and statistical accumulation and reference for future assembly of large-scale PCFCs.
