Solid oxygen fuel cells are a clean energy generation device with very high energy efficiency and if with hydrogen as fuel, the emission is zero. However, the utilisation of hydrogen is limited by on-board storage. Ammonia is a promising hydrogen carrier and can be directly fed to solid oxide fuel cells without fuel storage problem, and the products are just hydrogen and nitrogen. For direct ammonia solid oxide fuel cells, the key challenge is the anode. This project aims to develop a high performance anode for direct ammonia solid oxide fuel cells with both high activity and high stability at low temperature (below 600 degree C), thus addressing a key issue to make the direct ammonia solid oxide fuel cells commercially viable.Read moreRead less
