Abstract
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.
Description
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.
