Lanthanum-based hydrogen storage alloy is a metal hydride used for hydrogen storage. Rare earth hydrogen storage alloy powders typically consist of lanthanum (La), cerium (Ce), neodymium (Nd) and praseodymium (Pr) metals along with nickel (Ni) or cobalt (Co) and other transition metals. These alloys can absorb and release hydrogen, making them useful for hydrogen storage in fuel cells, electrolyzers and other hydrogen-based energy storage systems. Lanthanum-based hydrogen storage alloys have high hydrogen storage capacity, which makes them promising materials for efficient hydrogen storage at room temperature and relatively low pressure. Some of the advantages of using rare earth hydrogen storage alloys include: 1. High hydrogen storage density: Rare earth hydrogen storage alloys can store large amounts of hydrogen (up to 8 wt% or more) with high volume and weight densities. 2. High stability: These alloys are highly stable and can withstand multiple cycles of hydrogen absorption and desorption. 3. Safety and environmental protection: Compared with other materials that require high-pressure or low-temperature hydrogen storage, rare earth hydrogen storage alloys are safe, non-toxic and environmentally friendly. Overall, rare earth hydrogen storage alloy powders have the advantages of high hydrogen storage capacity, stability, safety, and environmental friendliness, and have great potential as alternative hydrogen storage materials.
Description
Hydrogen storage alloys are the materials that can absorb and desorb a large amount of hydrogen reversibly under certain temperatures and pressures. Metal hydride hydrogen storage device could utilize the alternative hydrogen absorbing ability of hydrogen storage alloys to achieve the solid form hydrogen storage.
