Ammonia borane (NH3BH3, AB) is a promising hydrogen source material due to its high hydrogen content (19.6 wt%). It is a white crystalline solid compound which was first synthesized and characterized by Shore and Parry [1] in the year 1955. The primary elements that make ammonia borane are nitrogen, hydrogen and boron. The elements nitrogen and hydrogen exist widely in the nature, e.g., in air and water [2]. Ammonia borane is a non-volatile material with appreciable degree of stability in air and water under ambient conditions.

    Nano-nickel Catalytic Dehydrogenation of Ammonia Borane
    (2014-02-12T05:09:49Z) NAYAK, DILEEP KUMAR; MANGALVEDEKAR, H.; MAHAJAN, S.
    The complex chemical hydride, ammonia borane (NH3BH3, AB) is a hydrogen rich compound. It is a promising hydrogen source for applications using proton exchange membrane fuel cells (PEMFCs) due to hydrogen content. It has reasonably lower operating temperatures compared with other solid-state hydriding materials. At present, AB is an expensive disposable source which in its pure form releases 1 mol of hydrogen at around 110 C.
