    摘要:

    系统研究了稀土系Ml-Ca-Ni(Ml:富镧混合稀土)储氢合金的储氢特性。实验结果表明,该系列合金吸放氢量大、动力学性能优良,其中,合金Ml0.8Ca0.2Ni5的吸放氢量可达180ml/g以上。以储氢合金Ml0.8C0.2Ni5氢化物作为氢的储存方式,研制了20Nm^3氢容量的车用燃料箱,以燃料箱作为氢源对汽油机进行台架对比试验,结果表明:氢-汽油混合燃料发动机可节省汽油30%,发动机相对热效率提高10%以上,发动机排出的CO含量减少70%以上,HC、NOx含量也降低;以燃料箱作为供氢系统进行了氢-汽油混合燃料车道路示范性试验。

    Abstract:

    The hydrogen storage properties of the alloys Ml-Ca-Ni (Ml: La-riched mischmetal) was systematically investigated. The experimental results show that the alloys Ml-Ca-Ni have good hydrogen storage capacity and hydriding/dehydriding kinetics. It was also found that the hydrogen storage capacity of Ml0.8Ca0.2Ni5 is more than 180ml/g. An automobile hydrogen storage tank used Ml0.8Ca0.2Ni5 hydride with hydrogen capacity of 20 Nm3 was designed and manufacted . The comparison test results reveal that with hydrogen-gasoline hybrid as its fuel, an gasoline engine may save gasoline by more than 30% and its thermal efficiency increases by more than 10%. Moreover, in its exhaust gases, the CO level decreases by 70% and the contents of HC and NOx also reduce. A demonstration test of a bus was carried out.
