A Study on the Performance of Matrix Prepared by Tape Cast and Its Molten Carbonate Fuel Cells (MCFCS)

用γ LiAO2 粉料和带铸法制备电池隔膜。隔膜有很高的阻窜能力和较低的欧姆极化。在电流密度为 2 0 0和 2 4 6mA/cm2 下放电时 ,用此膜组装的电池组 (三对电池 ,电极面积为 12 2cm2 )输出电压分别为 2 .0 1和 1.78V ,输出功率达 53.4W .于 2 0 0和 30 0mA/cm2 下放电时 ,单电池 (电极面积为 2 8cm2 )输出电压分别高于 0 .85和 0 .75V ,输出功率约 6 .6W .补偿隔膜收缩导致电池性能的提高 .The matrix prepared with γ LiAlO 2 powder and by tape cast displayed higher ability of preventing from gas cross over and lower ohmic polarization. The voltages of the stack (three cells,122 cm 2) stacked with the matrix were 2.02 and 1.78 V at 200 and 246 mA/cm 2, respectively, and the output power reached 53.4 W. The cell(28 cm 2) voltages were 0.85 and 0.75 V at 200 and 300 mA/cm 2, respectively,and the output power was about 6.6 W. Compensating the shrinkage of matrix in stacking cells promoted the enhancement of the MCFC performance.作者联系地址：中国科学院大连化学物理研究所!辽宁大连116023,中国科学院大连化学物理研究所!辽宁大连116023,中国科学院大连化学物理研究所!辽宁大连116023,中国科学院大连化学物理研究所!辽宁大连116023,中国科学院大连化学物理研究所!辽宁大连116023,中国科学院大连化学物理研究所!辽宁大Author's Address: Dalian Inst. of Chem.

熔融碳酸盐燃料电池组研究

以商用多孔烧结镍(铬)板为电极、自制γ-LiAlO2薄膜为电解质隔膜进行了熔融碳酸盐燃料电池的放大试验.有效面积为122cm2的3节串接电池组在973K和0.9MPa下,输出功率达到65W以上.工作电流密度为150mA/cm2时,平均单节输出电压达0.74V之上.工艺研究表明,电池组的性能随原料气压力或工作温度的提高而升高,但输出电压随原料气利用率的提高而下降

一种钒硅分子筛及其合成

一种新型的具有类ＺＳＭ－１２结构的钒硅分子筛，其结构式可表示为ｎＲ·(SixVy)O2，其中Ｒ为四乙基氢氧化铵，ｎ为摩尔数，且ｎ＝0.01～0.5;ｘ、ｙ分别为Ｓｉ、Ｖ的摩尔分数，且符合：ｘ＋ｙ＝１，ｘ＝０．９５０～０．９９９，ｙ＝０．００１～０．０５０。其合成方法是在无碱金属阳离子存在时，以四乙基氢氧化铵为模板剂、利用水热法直接制备。该钒硅分子筛对烃类选择氧化反应具有优良的催化性能。带填
