系统研究了稀土系Ｍｌ－Ｃａ－Ｎｉ（Ｍｌ：富铜混合稀土）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Ｍｌ０．８Ｃａ０．２Ｎｉ５氢化物作为氢的储存方式，研制了２０Ｎｍ３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。
The hydrogen storage properties of rare earth Ml-Ca-Ni (Ml: copper-rich mischmetal) hydrogen storage alloy were studied systematically. The experimental results show that the alloy has large hydrogen absorption and desorption capacity and excellent kinetic performance. The hydrogen absorption and desorption capacity of the alloy Ml0.8Ca0.2Ni5 can reach over 180 ml / g. Hydrogen storage alloy Ml0.8Ca0.2Ni5 hydrogen as a hydrogen storage method, developed a 20Nm3 hydrogen capacity car fuel tank. The bench test of the petrol engine with the fuel tank as the hydrogen source showed that the hydrogen-gasoline blend fuel engine could save 30% gasoline, the engine relative thermal efficiency increased more than 10%, the engine exhaust CO content reduced more than 70%, the HC, NOx The content is also reduced: The fuel tank as a hydrogen system was hydrogen-gasoline hybrid fuel vehicles road demonstration test.
