Current promising methods to release hydrogen from Ammonia Borane (NH3BH3, AB; 19.6 wt% H2) including neat thermolysis, thermolysis in ionic liquid bmimCl with or without proton sponge, thermolysis with nano-BN and hydrothermolysis, were investigated for hydrogen yield and ammonia formation. It was found that even trace moisture influences AB dehydrogenation significantly. The hydrothermolysis (13.5 wt% H2, 1 mol% NH3) at 85oC and thermolysis in bmimCl with 3 wt% moisture at 110oC (13 wt% H2, 0.2 mol% NH3) methods were found to be the most promising. This study demonstrates that AB dehydrogenation is an attractive approach to generate hydrogen for PEM fuel cell vehicle applications.
