查询词典 cobaltous oxide

A preparation method of nickel oxide-base cathode of fused carbonate fuel cell is to select alkali earth metal oxide, transition metal oxide and rare-earth metal oxide, mix with carbonyl nickel powder in the proportion of 0.01-15.00 mol%, add assistant and mix even into a slurry; after the slurry is formed into a biscuit by doctor-blade casting, sinter it into a multi-porous nickel plate; dissolve lithium nitrate and cobaltous nitrate with mole ratio of Li:Co-1:1 and citric acid or PVA in the distilled water to make a solution with Li of 0.00-0.5 mol/L; immerse the multi-porous nickel plate or nickel oxide plate in the solution, keep for 10-60 minutes under vacuum below 200 millibar, then dry in an oven at 75 degrees centigrade further transfer to a crucible electric furnace preheated 650 degrees centigrade for keeping the temp.

要約 熔融碳酸盐燃料电池氧化镍基阴极的制备方法属于燃料电池领域。选取碱土金属氧化物、过渡金属氧化物和稀土金属氧化物，按0.01－15.00mol％的比例与羰基镍粉混合，加入助剂，混合均匀成浆料；混合浆料流延成型为素坯后烧结为多孔金属镍板；将摩尔比为Li∶Co＝1∶1的硝酸锂和硝酸钴以及柠檬酸或聚乙烯醇溶于蒸馏水中，制成为0.005－0.5mol/L的溶液；将多孔金属镍板或氧化镍板浸入溶液中，在真空度低于200毫巴下保持10－60分钟；置于75℃的烘箱中烘干，转移至预热到650℃坩埚电炉中保温1－10小时；将此过程重复一次或多次即可。
