Hydrogen storage in hydride container is a complex process that can be addressed under different perspectives. Many efforts have been done so far to understand sorption phenomena of bulk hydride inside containers given that temperature and concentration profiles play an important role in assition to point-mass properties. In a previous article we defined a thermal optimization procedure for LaNi5 containers, based on a mathematical method and supported by experimental outcomes. The fraction of high conductivity material within the container, e. G., internal fin or metal foam, was evaluated in order to obtain the maximum absorption for fixed time and conditions. With this optimization procedure we designed and built a prototype of 200 NL capacity filled with MmNi4.7Al0.3 alloy. From preliminary results we confirm fast sorption reaction, both in absorption and desortion and discuss about performance and oissible apllications.
