Ammonia is a promising hydrogen carrier because of its high hydrogen density, low production cost, and ease in liquefaction and transport. Ammonia decomposes into nitrogen and hydrogen through a mildly endothermic process. The ammonia decomposition temperature is close to the operating conditions of solid oxide fuel cells (SOFCs). Therefore, the integration of these two devices is beneficial in terms of efficient heat and energy managements and will lead to the development of simplified generation systems. Continue reading

Applications of hydrogen permeable membranes in ammonia synthesis and decomposition

It is well known that ammonia is being considered as a method of storing hydrogen. Although some fuel cells are being developed that can use ammonia directly as a fuel source, many fuel cell technologies still require an outside cracker to revert ammonia back into hydrogen for efficient use. In this regard, hydrogen permeable membranes, such as Pd and its alloys, have been targeted as potential membrane reactors in which the ammonia is cracked while the hydrogen is simultaneously separated. Pd and its alloys are expensive, but offer potentially perfect hydrogen purity that is highly preferable for certain fuel cells susceptible to ammonia poisoning. Yet, cheaper metals, such as V, Nb and Ta, may offer a more affordable alternative while maintaining perfect hydrogen selectivity. The first part of this talk will involve our work on ammonia decomposition using both Pd-based membranes and the cheaper V, Ta or Nb metals. Continue reading

NH3 Fuel Conference, Los Angeles, September 19, 2016


Proton-conducting ceramics synthesized with solid-state reactive sintering are employed as electrolytes for the synthesis of ammonia from hydrogen and nitrogen gases in electrolytic cells. Additionally, these cells function with excellent long-term stability and high efficiency when operated in galvanic (fuel cell) mode using ammonia fuel. Advances in electrolyte compositions and synthesis techniques are discussed alongside cell performance metrics. Continue reading

Cracking ammonia

13th Annual NH3 Fuel Conference, September 19, 2016


In this talk, I will discuss our latest research in developing novel ammonia cracking catalysts. While ammonia can be used directly as a fuel in high temperature fuel cells, internal combustion engines and gas turbine, the ability to crack ammonia affordably and effectively increases the range of possibilities for utilising ammonia as an energy vector.
