Stability of LaNi5-xSnx cycled in hydrogen

In this work we study the effect of cycling in hydrogen with a purity grade 4.5 of six alloys belonging to the LaNi<inf>5-x</inf>Sn<inf>x</inf> family for 0 ≤ x ≤ 0.5. Measurements consist in the alternate repetition of absorption reactions at a temperature of 316 K and an in...
