This month the patent summaries have been made even briefer than they were before, in an effort to catch up most of the backlog of recently pubfished US and WO patents. It is encouraging that there is clearly so much research and development work going on in this very active area. We expect to return to more detailed summaries once most of the bacHog has been summarised. Hopefully the essential features of these new inventions are clear enough, even in this abbreviated form.

Supported Pt-Co-Cr alloy catalysts on graphitized carbon black showing increased activity and stability as electrode catalysts for oxygen-reduction reaction in phosphoric acid fuel cells have been developed by co-precipitation of the corresponding metal nitrates. XRD investigations showed that a tet

Potentiodynamic investigations have shown that the intermetallic compound Pt3Pb exhibited an activity approximately ten times higher than pure platinum in the anodic oxidation of ethylene glycol to oxalic acid. The results obtained with smooth electrodes have been confirmed with noble metal coated
The CoPtRu catalyst was prepared with electrochemical methods on carbon paper. The preparation of Co particles on the carbon paper was performed through an electrodeposition process by varying the deposition potential and time. After Co electrodeposition, Pt and Ru galvanic displacements were carrie
