Researchers at MIT believe developed a practical and physically-based way of treating the surface of materials called perovskite oxides,to make them more durable and improve their performance. These materials are promising candidates to serve as electrodes in energy-conversion devices such as fuel cells and electrolyzers. This surface treatment could solve one of the major challenges that has hindered widespread deployment of fuel cell technology that, when operated reversibly, and can present a promising alternative to batteries for renewable-energy storage.
