The high-temperature molten carbonate fuel cell is an ultra-clean and highly efficient power generator. It is operated at - 550-650 ℃, which is considered optimal in facilitating fast fuel cell reaction kinetics, utilizing waste heat efficiently, and allowing use of commercial construction materials. Commercial MW-size （mega watt） power plants of fuelcell Energy products have already been deployed worldwide. Metallic hardware materials are extensively utilized and may experience high-temperature reducing and oxidizing atmospheres in the presence of molten alkali carbonate electrolyte. Material selections are founded on many decades of focused research and development and field experience. Results to date show that the baseline stack module materials meet 5-year life goal and BOP （balance of plant） construction materials meet 20-year life goal. Material durability is well understood, and solutions are available to further extend the durability. This paper will review hardware materials experience and development approaches that would further reduce cost and extend life.

Functionalized exfoliated graphene oxide (EGO) for supercapacitor electrodes have been synthesized by simple chemical methods from the exfoliated graphite (EG) as precursor. Structural and morphological characterizations of EGO have been carried out using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), FTIR and Raman spectroscopy. Electrochemical performance of these electrodes has been investigated using cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy. The fabricated supercapacitor gave a specific capacitance of 146 Fg-1 and energy density of 20 Wh·kg-1 for a highly oxidized sample with more functional groups compared to pure, lower level oxidized and reduced samples. The single and multi layered graphene oxide sheets produced by this method have a lower degree of agglomeration. We found that the graphene oxide with functional oxygen groups of quinine type enhances the capacitance compared to other oxygen functional groups.

以铁氰化钾溶液作为电子受体,在阴阳两极室中分别填充石墨颗粒的基础上构建了填料型微生物燃料电池(Microbial fuelcell,MFC),研究了苯酚为单一燃料和苯酚+葡萄糖为混合燃料条件下MFC的产电特性以及对苯酚和COD的去除效果.在1000Ω外电阻条件下,1000mg·mL-1苯酚为单一燃料运行时,MFC在苯酚去除率达到约90%时输出电压达到最大值,最大输出电压为540mV,产电曲线存在单一极大值;以1000mg·mL-1苯酚+500mg·mL-1葡萄糖为混合燃料运行时,最大输出电压可达657mV,产电曲线存在2个峰值,第1峰值和第2峰值出现时对应的苯酚去除率分别约为20%和90%.混合燃料运行条件下,前后2个产电峰值出现时MFC的最大体积(面积)功率密度分别为28.3W.m-3(342.0mW.m-2)和12.6W·m-3(152.2mW·m-2),内阻分别为194Ω和246Ω.在2种燃料情形下,MFC对苯酚和COD的去除率均可在60h之内分别达到95%和90%以上.试验结果表明,MFC能够利用高浓度苯酚作为燃料,在实现高效降解的同时稳定地向外输出电能,这为酚类难降解有机物的高效低耗处理提供了新的研究思路.
