Johnson Matthey Fuel Cell's HiSPEC® catalysts consist of single and bimetallic, highly dispersed supported and unsupported catalysts used on anodes and cathodes in Polymer Electrolyte Fuel Cells (PEMFC) and Direct Methanol Fuel Cells (DMFC). HiSPEC catalysts are highly active and are designed and manufactured to the highest quality standards for maximum performance and durability.
HiSPEC Platinum 20% on Carbon - HiSPEC 3000 is most commonly recommended for use in the 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 or, as a building block for sensor elements.
The Fuel Cell Store is an authorized dealer for Alfa Aesar / Johnson Matthey products.
