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.

millibar：毫巴

拉薩的海拔高度是3650米,其平均大氣壓是645毫巴(millibar). 海平面的平均大氣壓是1015毫巴. 也就是拉薩的大氣壓只是上海的大氣壓的三分之二不到. 青藏鐵路的最高點的海拔是5072米,那里的大氣壓是535毫巴.
