Abstract :
In this paper, we present an accurate sensor used to monitor the concentration of hydrogen in a LaNi5 solid-state hydrogen storage device. The monitoring technique is based on the variations of the electrical properties of the storage material related to the hydrogen content. The sensor uses the electrical resistance of the sample which is directly linked to the hydrogen concentration. A finite element model is presented to simulate the resistivity variations during hydrogenation.
