Tokyo, Japan, Apr 1, 2008 - (JCN Newswire) - Hitachi Maxell, Ltd. (TSE: 6810) has announced development of a new catalyst used for oxygen-reduction reactions at the cathode of a polymer electrolyte fuel cell (PEFC). The new catalyst is gold-platinum (AuPt) nano-particle 2 to 3 nm in size and can generate approximately 4.8 times the oxygen-reduction current per unit area than commercial platinum catalysts.
PEFCs are a promising clean-energy source for automobiles, homes, and mobile devices. Platinum is commonly used as the catalyst for the oxygen-reduction reaction in PEFCs, but platinum is an extremely expensive precious metal, so reducing material cost for PEFCs ...
