A recent study conducted at Fuzhou University and published in Frontiers in Energy introduces a novel approach to boost the performance of direct ammonia protonic ceramic fuel cells (DA-PCFCs). By incorporating a CeO2-supported Ni and Ru catalyst layer, researchers have successfully enhanced the electrochemical performance of these cells, marking a significant stride towards sustainable energy solutions. The study focused on the development of a CeO2-supported catalyst layer to revamp the anode surface of DA-PCFCs, aiming to address the challenge of achieving satisfactory performance at intermediate temperatures. The research team investigated a PCFC using ammonia as fuel within a temperature range of 500–700°C and observed a notable improvement in electrochemical performance with the M(Ni,Ru)/CeO2 catalyst layer. Results indicated that Ru-based catalysts exhibit more promise for direct ammonia solid oxide fuel cells at temperatures below 600°C, although the improvement diminishes above 600°C compared to Ni-based catalysts. The study showcases the potential of CeO2-supported catalysts to elevate the performance of DA-PCFCs, offering a pathway towards more efficient and sustainable energy conversion systems. This advancement not only tackles technical hurdles linked to ammonia fuel cells but also propels the development and commercialization of eco-friendly energy technologies.
