Fuel cell catalyst
Platinum is considered the standard metal for fuel cells. Platinum is considerably more effective than silver and gold at converting hydrogen and oxygen into water and electricity. Platinum Ruthenium Alloy, the most effective catalysts for oxidation and reduction reactions, when dispersed evenly in carbon powder, increase reactive surface area significantly and provide an ideal catalyst for many electrochemical processes. Fuel cells create power by oxidizing hydrogen atoms into protons and electrons on the anode electrode and reduced oxygen atoms with protons on the cathode electrode. Generally, in a Polymer Electrolyte Membrane Fuel Cell (PEMFC), Platinum is used as the catalyst. A Direct Methanol Fuel Cell (DMFC) requires the addition of Ruthenium as a catalyst. It is used to promote the oxidation and redirection reactions.
