Demonstrating hydrogen production from ammonia using lithium imide Powering a small proton exchange membrane fuel cell
Abstract Accessing the intrinsic hydrogen content within ammonia, NH3, has the potential to play a very significant role in the future of a CO2 free sustainable energy supply. Inexpensive light metal imides and amides are effective at decomposing ammonia to hydrogen and nitrogen (2NH3 3H2 N2) at modest temperatures, and thus represent a low cost approach to on demand hydrogen production. Building upon this discovery, this paper describes the integration of an ammonia cracking unit with a post reactor gas purification system and a small scale PEM fuel cell to create a first bench top demonstrator for the production of hydrogen using light metal imides.
