A novel combined system integrated with SOFC/GT is proposed,which employs the double heat source Kalina cycle to recover the waste heat from SOFC/GT and the membrane separation of N2 or CO2 to obtain the oxygen-enriched air and low CO2 emissions.The mathematical model for the proposed system is developed by using the EES software and the system performance isstudiedbased on the first and second laws of thermodynamics.The parametric study is also conducted to investigate the influence of the main parameters,such as O2 purity of oxygen-enriched air,the fuel utilization factor,on the system performance.The results indicate thatthe SOFCelectricalefficiencyof the proposed system is 51.24%,increased by 1.23%in comparison with that of the reference system.The exergy analysis results show that the largest exergy loss occurs in membrane separation device of N2 followed by the gas turbine,the medium temperature waste heat boiler and combustion chamber.

石墨烯是由碳原子按六角结构蜂窝状紧密排列而成的二维单层石墨,其独特的结构和优良的理化性质吸引了越来越多研究者的兴趣.石墨烯超强的电子导电性和良好的稳定性也使得它有望成为燃料电池中很好的催化剂载体[1-4].本工作以SiO2为牺牲模板,通过在模板外面均匀包覆Pt纳米粒子和石墨烯,然后除去模板的方法,得到石墨烯包裹Pt的纳米催化剂.制备得到的石墨烯包裹的Pt纳米结构催化剂(GO@Pt)对甲醇氧化显示了
贵金属纳米结构物在催化剂领域中已经得到了广泛的应用.通过调控其化学组成,特别是通过对二元贵金属核壳纳米结构物设计调控其组成和形貌,一般情况下它们会比单组份化合物有提高的催化活性,这主要归功于其几何效应,电子效应以及其组分间的协同效应.在各种各样的核壳纳米结构物中,组分是Au和Pd的二元纳米金属结构物在催化剂研究领域已有广泛的关注.
直接液体燃料电池以其燃料来源广、能量转换效率高、低污染和易存储运输等优点,同时解决当前社会面临的环境污染和能源短缺两大难题而受到广泛关注.但电池电极催化剂活性低、易毒化、价格高等因素,制约着燃料电池的商业化应用与发展.提高催化剂活性和降低贵金属使用量成为目前研究的重点1-5.本论文利用聚烯丙基胺盐酸盐(PAH)作为稳定剂与形貌控制剂、甲醛作为还原剂来还原CuCl2和K2PtCl4前驱体,一步法成功
