Describes the chemical physics of fuel cell reactionsFormat: Hardcover. Electrocatalysis is a catalytic process involving oxidation and Electrocatalysis of fuel cell reactions book reactions through the direct transfer of electrons, which requires electrocatalysts to lower the overpotential of the reactions.

An electrocatalyst can accomplish the surface catalytic reaction through different reaction pathways with different thermodynamic potentials. An electrocatalyst is used in an electrochemical reaction, for example in a fuel cell to produce electricity. In this case, reaction rates are also dependent on the electrode potential and the structure of the electrical double-layer.

The opening chapters introduce the essential topics on electrochemical theory and fuel cell catalysis, including: electrode thermodynamics, kinetics, and mass transfer; electrode/electrolyte interface electrocatalysis; electrocatalytic reactions, including O 2 reduction and H 2 /CH 3 OH oxidations; quantum chemistry simulations of catalyst.

These plates must be low weight and low cost while being stable in the aggressive conditions met within the fuel cell. Catalysts speed up a chemical reaction or allow for reactions to take place that would not otherwise occur. The chemical nature of a catalyst and its structure are crucial for interactions with reaction intermediates.

An electrocatalyst is used in an electrochemical reaction, for example in a fuel cell to produce : Wiley. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions.

Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes.

The sluggish kinetics of oxygen reduction reaction is one of the main reasons for the high overpotential in a hydrogen proton exchange membrane fuel cell.

In other types of low temperature fuel cells, for instance direct alcohol fuel cells, the slow fuel oxidation reactions is another major contribution to their low performance. We explore basic problems of electrocatalysis of fuel cell reactions, while focusing on platinum monolayer (PtML) electrocatalysts for the O 2 reduction reaction (ORR), the electrocatalysts for ethanol and methanol oxidation to CO 2, H 2 evolution (HER) and H 2 oxidation (HOR) reactions.

The goals include developing the fundamental. Fuel cell science is undergoing significant development, thanks, in part, to a spectacular evolution of the electrocatalysis concepts, and both new theoretical and experimental methods.

Alloys of Pt have been shown to improve the kinetics of oxygen reduction. We have found that the deposition of Zn onto Pt creates a substrate upon which we have measured the kinetic parameters for the electrodeposition of Zn under close-to-industrial conditions. We are now studying the chemical nature of the surface alloy using UHV techniques such as Auger.
