Hydrogen Storage Alloy
Nov 09, 2018

A hydrogen storage alloy capable of reversibly storing hydrogen, the composition of which is TiaVbCrcAldMe, wherein M is at least one element or two elements of Cu, Fe, Co, Ni, Si, Sn, Mo, W, 1.0 ≤ a ≤ 1.6, 0.2 ≤ b ≤ 1.0, 1.0 ≤ c ≤ 1.6, 0.01 ≤ d ≤ 0.5, 0.01 ≤ e ≤ 0.5. The hydrogen storage alloy of the present invention can be smelted by a vacuum arc furnace and a vacuum intermediate frequency induction furnace, and can be cast by vacuum suction casting. The smelted alloy is easily activated and has a maximum hydrogen storage capacity of 4.0% by weight. The alloy is suitable for use as a hydrogen purifier alloy and a fuel cell hydrogen source alloy.

Hydrogen is one of the best choices for future energy. The use of hydrogen energy involves the storage, transport and use of hydrogen. Since the reversible hydrogen storage of intermetallic compounds such as LaNi5 and FeTi was discovered in the mid-1960s, hydrogen storage alloys and their applications have been rapidly developed. Hydrogen storage alloys can absorb hydrogen in the form of metal hydrides, which is a safe, economical and effective hydrogen storage method. Metal hydride not only has hydrogen storage characteristics, but also has the function of converting chemical energy and thermal energy or mechanical energy into each other, so that the chemical storage and transportation of thermal energy can be developed by utilizing the enthalpy change in the reaction process, and the low-quality heat source of various waste heat forms can be effectively utilized. . Therefore, many applications of hydrogen storage alloys have received attention.
