The global efforts to combat energy and climate challenges have propelled the exploration of carbon-free energy carriers, with hydrogen being a prominent contender. However, ammonia has emerged as a promising alternative with its high hydrogen content and economic efficiency. Unlike hydrogen, ammonia offers easier storage and transportation at lower pressures and temperatures, making it a viable option for energy applications. Ammonia fuel cells, particularly Direct Ammonia Fuel Cells (DAFCs), are gaining traction for their potential to provide carbon-neutral energy solutions with water and nitrogen being the only byproducts. Despite the advantages of ammonia, challenges such as catalyst development, reaction efficiency, and cost-effectiveness hinder its large-scale commercialization. To address these obstacles, ongoing research focuses on optimizing catalysts, improving reaction kinetics, and reducing precious metal dependency. Enhancing the efficiency and affordability of ammonia fuel cells is crucial for their practical implementation in various industries, including automotive and energy sectors. Overall, ammonia fuel cells offer a promising direction for the future of energy technology, with continued advancements needed to overcome existing hurdles and facilitate their widespread adoption.
