40% Platinum on High Surface Area Ketjenblack EC-300J

The ability to prepare well dispersed, high surface area electrocatalysts containing platinum has significantly increased the viability of many electrochemical processes.  This new process provides an outstanding, high purity catalyst that is amenable to forming highly uniform electrode structures.

Suggested Uses
40% Platinum on High Surface Area Ketjenblack EC-300J is most commonly used for Polymer Electrolyte Fuel Cell (PEMFC), Direct Methanol Fuel Cell (DMFC), Microbial Fuel Cell (MFC), and Phosphoric Acid Fuel Cell (PAFC) applications (as the cathode catalyst or anode catalyst).  It is also used as a recombination catalyst for hydrogen elimination.  Platinum on Vulcan can also be used as a building block for sensor elements.
