Electrocatalysis in Fuel Cells

Enhanced electrocatalysis of oxygen reduction on platinum alloys in proton exchange membrane fuel cells *

Enhanced electrocatalysis of the oxygen reduction reaction (ORR) on carbon-supported binary and ternary alloys of Pt in phosphoric acid fuel cells has been reported previously. This investigation focuses on the electrocatalysis of the ORR on some binary alloys of Pt (Pt+Ni, Pt+Cr and Pt+Co) at interfaces with proton exchange membranes (Dow perfluorinated sulfonic acids). Comparison of the resul...

Alkaline Methanol Fuel Cell Electrocatalysis Using a Pressurized Electrochemical Cell

Electrocatalysis in DNA Sensors.

Electrocatalysis is often thought of solely in the inorganic realm, most often applied to energy conversion in fuel cells. However, the ever-growing field of bioelectrocatalysis has made great strides in advancing technology for both biofuel cells as well as biological detection platforms. Within the context of bioelectrocatalytic detection systems, DNA-based platforms are especially prevalent....

BESH2002 Catalysis and Electrocatalysis for Fuel Synthesis: Hydrogen Production and the Water-Gas Shift

The water-gas shift reaction (WGS: CO + H2O  H2 + CO2) is a critical process in providing pure hydrogen for fuel cells and other applications. Improved air-tolerant, cost-effective WGS catalysts for lower temperature processing are needed. Ceria-, titaniaand molybdena-based catalysts are expected to be the next generation of WGS catalysts for industrial applications. The design and optimizatio...
