Preparation of Nanometric Oxides that Exhibit Enhanced Protonic Conductivity at Low Temperatures
Researchers at the University of California, Davis have developed a novel method to fabricate nanometric oxides that exhibit enhanced conductivity. Conduction in these materials (e.g., cubic zirconia and other materials with similar properties) takes place by protonic movement as opposed to ionic mobility, making it possible to operate a fuel cell at much lower temperatures. The marked reduction of the resistivity in these materials at low temperatures are comparable to that typical of other protonic conductors but with the advantage of superior mechanical properties, chemical stabilities, and the lack of a need for a catalyst.
