SMARTCAT

The present consortium will build a new concept of electrodes based on new catalyst design (ternary alloyed/core shell clusters) deposited on a new high temperature operation efficient support. In order to enhance the fundamental understanding and determine the optimal composition and geometry of the clusters, advanced computational techniques will be used in direct combination with electrochemical analysis of the prepared catalysts. The use of deposition by plasma sputtering on alternative non-carbon support materials will ensure the reproducible properties of the catalytic layers. Plasma...

NANO-CAT

Many efforts have been put on the reduction of the Pt loading but nowadays a threshold seems to be obtained. Because the kinetics of the Hydrogen Oxidation Reaction is very fast on Pt, it is possible to use MEA with a Pt loading as low as 35 µgPt/cm-2 without any effect on the voltage loss when such an anode is used in front of a well working cathode. But, the Oxygen Reduction Reaction kinetics is not so fast which is the limiting step concerning the electrochemical processes in a PEMFC. For that raison, the decrease of the Pt loading is now encountering a plateau. Nano-CAT will propose...
