摘　　要：熔融碳酸盐燃料电池(MCFC)作为大规模民用发电装置而备受瞩目。但MCFC自身也存在一些缺陷,其中阴极材料NiO在高温熔融盐电解质中会随着长时间的使用慢慢溶解,在阴极的表面析出金属Ni、与阳极材料金属Ni形成类似搭桥的构造,因而造成电池短路。由于MCFC的自身特点,可以使用沼气等工业废气作为反应燃料。在熔融碳酸盐中导入SO2气体可以影响阴极材料的稳定性。Molten carbonate fuel cell(MCFC)has attracted much attention as a large-scale civil power generation device.However,there are some defects in MCFC.The cathode material NiO will dissolve slowly in high temperature molten salt electrolyte with a long time,and the metal Ni will precipitate on the surface of the cathode and form a bridge with the metal Ni of the anode material,thus resulting in short circuit of the battery.Due to the characteristics of MCFC,industrial waste gas such as methane can be used as reaction fuel.Therefore,SO2 gas is introduced into molten carbonate to investigate its influence on the stability of cathode materials.
