中国化学会第27届学术年会

作者： Tsuyohiko Fujigaya Kazuya Matsumoto naotoshi Nakashima Department of Applied Chemistry Graduate School of Engineering Kyushu University JST-CREST 5 Sanbancho Chiyoda-ku Tokyo 102-0075 Japan Department of Applied Chemistry Graduate School of Engineering Kyushu University

Polybenzimidazole （PBI: Fig. 1） is widely known as a promising candidate for electrolyte membrane of polymer electrolyte fuel cell （PEFC） operating under dry condition. On the other hand, carbon nanotubes （CNTs） have been emerged as a better carbon support material than conventional material such as carbon black. We have reported the PBI is adsorbed onto the surface of CNTs and acts as the good solubilizer [1]. By taking advantage of stable wrapping of PBI on CNTs, we utilized this composite as a novel carbon supporting materials for loading the metal catalyst such as platinum （Pt）. As the result, the PBI-wrapped CNTs show better efficiency of Pt loading than that of pristine CNTs due to the coordination between Pt ion and PBI. Furthermore, the obtained electrocatalyst （CNT/PBI/Pt） shows excellent Pt utilization efficiency mainly due to the formation of ideal interfacial structure constructed by the CNTs, PBI and Pt [2]. However, we also noticed the electrochemically active area （ECSA） was gradually decreased during long time operations caused by the aggregation of the Pt.

燃气轮机联合循环热效率的提高,要求涡轮进口温度不断增加。目前,三菱重工(MHI)已经积极参与日本国家项目,通过发展1700℃级燃气轮机,以使联合循环热效率实现达到62%指标。在此国家项目中开发的部分组件技术适用于1600℃级燃气轮机M501J,它具有世界上最高的涡轮进口温度。而热障涂层(TBC)是实现此目标的最关键技术之一。在发展先进的热障涂层中,在MHI工厂中建立名为T点的试验电厂是有必要的。在真实热部件中制备的先进TBC可以在工厂中进行验证,并且运行后的效果可以得到反馈。本文讨论了TBC的开发以及在三菱重工实际电厂中的验证。

目的在氯化胆碱-乙二醇(ChCl-2EG)低共熔溶剂(DESs)中,以水为添加剂,采用电沉积制备Zn-Fe合金镀层,改善镀层的表面形貌,优化晶型结构,提高镀层的耐蚀性能。方法采用电导率仪、黏度计、循环伏安曲线(CV)研究水含量对低共熔溶剂黏度、电导率、电化学窗口的影响。采用扫描电子显微镜(SEM)、能谱仪(EDS),研究水含量对镀层表面形貌和成分的影响。采用X射线衍射仪(XRD),分析水含量对镀层结构特征的影响。采用动电位极化曲线和电化学阻抗谱(EIS),分析水含量对镀层耐蚀性能的影响。结果随着水含量的增加,DESs的黏度降低,电导率升高,镀速增大,镀层中Zn含量提高,平均晶粒尺寸减小。当水的质量分数小于8%时,水会促进Zn和Fe的沉积。当水的质量分数大于8%时,水会抑制Zn和Fe的沉积。此外,当水的质量分数为4%时,DESs能够保持原有的电化学窗口(2.47 V),制备的Zn-Fe合金镀层平整致密,镀层极化电阻达到最大值(1469Ω/cm^(2)),电荷转移电阻达到最大值(612Ω/cm^(2)),耐蚀性最佳。结论水的含量会影响DESs溶剂的黏度、电导率及电化学窗口,会影响Zn-Fe合金镀层的表面形貌、晶粒尺寸及耐蚀性。当加入质量分数4%的水时,不仅能够促进Zn和Fe还原,而且还能改善Zn-Fe合金镀层的表面形貌,提高镀层的耐蚀性能。
