Abstract

<p>Platinum is used for the electrode materials of PEFCs. However, platinum is expensive and its resource is limited. Platinum is unstable in an acidic media and has not enough catalytic activity especially for oxygen reduction. Platinum is also not environmentally friendly, since it consumes huge energy to produce platinum metal. A development of a new catalyst without a platinum group metal is very important for the large distribution of fuel cells. Group 4 and 5 metal oxide-based materials might be good candidates for the new cathode material of a PEFC, since they have high stability in an acid media and relatively high catalytic activity for oxygen reduction.</p>
