Researchers from the University of Oklahoma have made significant advances in a promising technology for efficient energy conversion and chemical processing. Two recent studies involving protonic ceramic electrochemical cells, called PCECs, address significant challenges in electrochemical manufacturing and efficiency. These innovations are a crucial step toward reliable and affordable solutions for hydrogen production and clean energy storage.

The studies were led by Hanping Ding, Ph.D., an assistant professor in the School of Aerospace and Mechanical Engineering at the University of Oklahoma.

PCECs have traditionally struggled to maintain performance under the extreme conditions required for commercial use. In a study featured in Nature Synthesis, Ding and his colleagues reported a new approach that eliminates the need for cerium-based materials, which are prone to breakdown under high steam and heat.
