Novel Non-noble Cathodes for Polymer Electrolyte Fuel Cell
Prof. Ishihara and co-workers from Yokohama National University, reported their study on Electrochimica Acta, which was about non-noble fuel cell electrode using a new Ta-O based material[1].
Though Pt drew a lot of attraction as a fuel cell catalysts, it is essential to develop a new non-noble material instead of using Pt due to its high price.
Prof. Ishihara and co-workers treated Ta-CN with high temperature condition under an oxygen atmosphere and succeeded in its catalytic performance enhancement. By compared its redox potential to ionization potential, which is measured by AC-3, the best treatment condition was known from a volcanic-related plot.
Therefore, AC-3 can be your best partner and contribute to those advanced materials development.
