摘　　要：制备了金属陶瓷双相Ni-BaCe0.6Zr0.2Nd0.2O3-δ膜,并将其用于从含氢混合气中分离氢气,研究了该膜在不同条件下的透氢性能以及膜片在CO2与H2O存在条件下的透氢稳定性.结果表明,膜片的透氢量随着温度的升高而提高.当使用含3%H2O的原料气时,膜片透氢量是其在干燥气氛时的2～5倍;在900°C,原料气为潮湿80%H2/He的条件下,膜片的透氢量达到0.073cm3/(mincm2).膜片在含有30%CO2的混合气中,经100h寿命实验后,仍然保持较高的渗透稳定性.这些结果表明该双相膜在分离CO2和H2混合气中具有很好的应用前景.A new V（Ni-BZCN6） cermet membrane was investigated to separate hydrogen from hydrogen-containing mixtures. Hydrogen permeation properties of the membrane and permeation stability under atmospheres containing CO2 and H2O were investigated under different conditions. Hydrogen permeation flux increases with increasing temperature. When the feed gas was moistened by 3% H20, the flux was about 2-5 times that not moistened. It reached 0.073 cm^3/（min cm^2） at 900℃ when a wet feed gas of 80% H2/He was used. After 100 h operation under 30% CO2, the membrane still keeps a steady permeation flux. These results suggest that the Ni-BZCN6 membrane is suitable for hydrogen separation from mixed gas containing H2 and CO2.
