| 1 | H_2S燃料电池用质子传导膜及电池性能显示文摘研究了H2S燃料电池用的质子传导膜的制备及性能,考察了不同的Li2SO4与填充物Al2O3的匹配、微量元素B(H2BO3)的掺杂对膜及电池性能影响.研究了由H2S、(MoS2+NiS)/Li2SO4-Al2O3/pt、air构成的燃料电池在101.13kPa和600~700℃C时的电化学特性.在实验温度范围内,质子传导膜Li2SO4-Al2O3及整个电池系统在H2S气流下具有较好的化学稳定性.温度提高,质子传导膜的内阻减小,膜及电池性能变好.微量元素B的掺杂提高了膜的机械强度及膜的致密性,从而改善了电池的性能.在实验条件下,较适宜的B的掺杂量为2%~5%(质量百分数),较适宜的Li2SO4:Al2O3(质量比)为(3~5):1,电池最大输出电流密度和功率密度在700℃时分别达到200mA.cm-2和55mW.cm-2. | 钟理 张腾云 WEI Guoling Chuang Karl | 2004 | 高校化学工程学报2004，18，2： | 14 |
| 2 | Influence of Metal Sulfides as Anode Catalysts on Performance of H_2S SOFC显示文摘Two anode catalysts with Pt, MoS2 and composite metal sulfides (MoS2+NiS), are investigated for electrochemical oxidation of hydrogen sulfide in solid oxide fuel cell (SOFC) at temperatures 750-850℃. The catalysts comprising MoS2 and MoS2+NiS exhibited good electrical conductivity and catalytic activity. MoS2 and composite catalysts were found to be more active than Pt, a widely used catalyst for high temperature H2S/O2 fuel cell at 750-850℃. However, MoS2 itself sublimes above 450℃. In contrast, composite catalysts containing both Mo and transition metal (Ni) are shown to be stable and effective in promoting the oxidation of H2S in SOFC up to 850℃. However, electric contact is poor between the platinum current collecting layer and the composite metal sulfide layer, so that the cell performance becomes worse. This problem is overcome by adding conductive Ag powder into the anode layer (forming MoS2+NiS+Ag anode material) to increase anode electrical conductance instead of applying a thin laver of platinum on the top of anode. | 钟理 刘曼 韦国林 CHUANG Karl | 2003 | Chinese Journal of Chemical Engineering2003，11，3： | 9 |
| 3 | 固体氧化物质子传导膜H_2S燃料电池显示文摘A brief overview of the past and present state of art in the field of H2S solid oxide fuel cell is presented.Electrochemical performance of a proton-conducting solid oxide fuel cell having the configuration of H2S,(MoS2+NiS)/Li2SO4-Al2O3/Pt,air was investigated.The experimental results showed that electrolyte materials like Li2SO4-Al2O3, and anode substances such as MoS2+NiS showed good chemical stability under the operating conditions of a fuel cell using H2S as the fuel, and that binary metal sulfides such as MoS2+NiS as an anode catalyst was superior to a single metal sulfide of MoS2 which sublimes above 450 ℃, and better than Pt which could be detached and resulted in the degradation of anode due to the formation of PtS.The proton-conducting and cell performance was improved at elevated temperatures due to the increase of electrochemical reaction rate and the reduction of cell resistance.OCV values around 1.0 V were observed.The maximum current and power density values obtained at 600 ℃ were 20 mA·cm -2 and 4 mW· cm -2, and as high as 200 mA· cm -2 and 55 mW· cm -2 were achieved at 700 ℃, respectively.Three different anode catalysts, Pt, MoS2+NiS and MoS2+NiS+Ag were described.The conductance of cell increased and the cell performance was improved with Ag powder added to anode catalysts.Current density up to 250 mA· cm -2 and power density up to 70 mW· cm -2 were achieved with the anode catalyst MoS2+NiS+Ag compared to those with MoS2+NiS at 700 ℃. | 钟理 陈建军 WEI Guolin LUO Jingli CHUANG Karl | 2004 | 化工学报2004，55，10： | 6 |
