摘　　要：研究了LaNi5+x%TiMn1.19(质量百分比,下同)(x=5,10,15,25)合金的贮氢性能,研究结果表明:由于TiMn1.19合金的加入,有效地降低了贮氢材料的平台压力,当TiMn1.19的含量为15%左右时,室温下合金的平台压力近于0.1MPa,适于作为负极贮氢材料使用。The hydrogen storage characteristics of the alloys LaNi_5+x(wt)%TiMn_ 1.19(x=5,10,15,25) were investigated. The results show that the hydrogen storage material plateau pressure is decreased effectively because of the addition of TiMn_ 1.19. At room temperature the plateau pressure of the LaNi_5+15(wt)%TiMn_ 1.19 alloy approaches to 0.1MPa . The hydrogen storage alloy can be used as cell cathode.
