Ammonia Fuel Cells Get Catalysed
Ammonia is a potentially rich source of hydrogen for fuel cells. All it needed was a good catalyst that would reform NH3 into Hydrogen and Nitrogen.
Pure hydrogen is difficult to handle, for small vehicular uses. But hydrogen reformed from methane, methanol, ammonia, etc. is extremely manageable.
The HYPERMEC 10010 is a ruthenium-based catalyst which delivers ammonia conversion at 400°C. This catalyst is available in powder or pellet form. The current pre-commercial base metal catalyst HYPERMEC 10510 will offer ammonia conversion at a lower cost at slightly higher temperatures, and is expected to be available to customers by the end of 2008._GCC

storage of ammonia has many problems..toxicity and flammability/explosion among them.
Better: urea. NH2-CO-NH2, catalyzed to CO2 & NH3 by common enzyme urease.
Stores easily as a very conc water solution.
