Catalysts

Description:

The fuel cell creates power by oxidizing a hydrogen atom into a proton and an electron on anode electrode and reduced oxygen atom with proton on cathode. In a PEM fuel cell, Platinum is used as the catalyst. A direct methanol fuel cell requires the addition of Ruthenium as a catalyst. It is used to promote the oxidation and redirection reactions. Electro catalysts for fuel cell applications contain 10 % or 20 % Pt on VULCAN XC-72R carbon support. Typical electro- chemical area (ECA) for 20 % Pt/C is 100 m²/g. Typical ECA for 10 % Pt/C is 140 m²/g.
Pt/Ru electro-catalysts carbon monoxide tolerant electro-catalyst for direct methanol fuel cell applications contains 20 % Pt and 10 % Ru (50:50 atomic ratio) on VULCAN XC-72R carbon support. 20 % Pt and 10 % Ru catalyst exhibits better resistance to CO poisoning and it is well suited for direct methanol conversion fuel cells. The catalyst can also be used in fuel cells operating in conjunction with gas reformers.
