Abstract
Electrochemical hydrogen loading is a technique used to produce and study the hydrogenation
in metals starting from a liquid solution containing water. It is a possible
alternative to another, well-established technique which loads hydrogen starting from
its gas phase. In this work, the electrochemical method is used to understand the fundamental
thermodynamics of hydrogen loading in constraint systems such as thin films
on substrates, and possibly distinguish the role of interfaces, stresses and microstructure
during the hydrogenation process. The systems under study are thin films of Pd, Mg/Pd,
and Ti/Mg multilayers. Possible future technological applications may be in the field
of hydrogen storage and hydrogen sensors. Towards the end, the experimental setup is
modified by introducing an automatic relay. This change leads to improvements in the
data analysis and in the attainable information on the kinetics of the systems.
