Researchers at the California Institute of Technology have discovered that ceria (or cerium dioxide) is an excellent catalyst for fuel cell anodes. This discovery was made through careful electrochemical characterization using a.c. impedance spectroscopy, an important tool for studying the electrical transport behavior of ceramics. The study is published in the Journal of the American Ceramic Society.
