Influence of surface barriers on hydrogen storage in MgAl films on permeable stainless steel membranes

The structural modifications and formation of hydrides were identified in the plasma hydrided MgAl films using X-ray diffraction. The hydrogen distribution profiles were investigated in the MgAl films and stainless steel membranes employing glow discharge optical emission spectroscopy. Thermal desorption analysis revealed the hydrogen effusion kinetics.
