Direct Ammonia Fuel Cells (DAFC); A Solution to Global Warming and Energy Crisis (Advert Reference: RDF21/EE/MCE/BAYATIMaryam)


Faculty of Engineering and Environment

About the Project

The depletion of energy resources and environmental pollution are urgent problems in contemporary society. Hydrogen fuel cells have been recognized as clean energy-converting devices due to their high efficiency and zero emissions, which makes them a promising technology to combat the above-mentioned global challenges. However, hydrogen is difficult and expensive to store in bulk and distribute.

Ammonia is a cost effective, commercially available with zero-carbon emission fuel and an energy vector which unlike hydrogen, all the infrastructure for its storage and distribution exist.

To date, the most effective catalyst for ammonia electro-oxidation (AEO) has been platinum which its cost and scarcity limits the commercialization of DAFCs.

The aim of this project

is on developing catalysts with low Pt loading. Recently, for the first time, our group has synthesised a high surface area with low-load of Pt composite which outperformed high surface area Pt/C catalyst for AEO[1].
The focus of the project will be on explore and synthesis of this novel class of transition metal carbide and nitride with noble metal composite based on the reported DFT calculations, for their application in AFC. The efficiency and specific energy density (energy per unit mass) of these fuel cells will be further increased by employing graphene aerogel material[2].

The work packages will include

mainly hydrothermal synthesis of composite catalysts and graphene aerogel, DAFCs simulations, material characterisation, and testing DAFC.

Key technologies used in research work packages are:

• Composite catalyst and graphene aerogel synthesis (Hydrothermal and etc.)
• Materials characterisation: Electrochemical testing (CV, LSV, Chronoamperometry), SEM, TEM, XPS, Profilometer, Ellipsometry
• DAFC Simulation: FEA (ABAQUS, ANSYS, COMSOL)
• Testing DAFCs

The principal supervisor for this project is Dr. Maryam Bayati.
