Researchers have developed a groundbreaking catalyst coating technology for solid oxide fuel cells that drastically enhances performance within just four minutes. The technology, which employspraseodymium oxide catalysts, targets the oxygen reduction reaction at the air electrode, increasing the power output of SOFCs significantly.
Fuel cells are gaining attention as highly efficient and clean energy devices driving the hydrogen economy. Among them, solid oxide fuel cells , which have the highest power generation efficiency, can use various fuels such as hydrogen, biogas, and natural gas. They also allow for combined heat and power generation by utilizing the heat generated during the process, making them a subject of active research and development.
Additionally, the research team elucidated the mechanism by which the coated nano-catalyst promotes surface oxygen exchange and ionic conduction. They provided fundamental evidence that the catalyst coating method can address the low reaction rate of the composite electrode.
