Platinum Ruthenium - Model PtRu -50/50

Platinum Ruthenium (Pt 50%, Ru 50%) is most commonly used for Polymer Electrolyte Fuel Cell (PEMFC), Microbial Fuel Cell, and Phosphoric Acid Fuel Cell 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.
