Fuel cells are one of the most promising clean energy conversion devices that can solve the environmental and energy problems in our society. However, the high platinum loading of fuel cells - and thus their high cost - prevents their commercialization. Non- or low- platinum electrocatalysts are needed to lower the fuel cell cost. Electrocatalysis in Fuel Cells: A Non and Low Platinum Approach is a comprehensive book summarizing recent advances of electrocatalysis in oxygen reduction and alcohol oxidation, with a particular focus on non- and low-Pt electrocatalysts. All twenty four chapters were written by worldwide experts in their fields. The fundamentals and applications of novel electrocatalysts are discussed thoroughly in the book. The book is geared toward researchers in the field, postgraduate students and lecturers, and scientists and engineers at fuel cell and automotive companies. It can even be a reference book for those who are interested in this area.

Due to the steady depletion of mineral fuels and the environmental pollution from conventional engines, there have been great interests in developing fuel cells. At present, the direct methanol fuel cell (DMFC) is one of the leading fuel cell systems. Currently, the widely used electrocatalyst for the DMFC is the Pt/Ru bimetallic system. But the disadvantages of Pt/Ru catalyst are its high costs, and its susceptibility toward CO poisoning due to the strong chemisorption of CO. Therefore, an alternative electrocatalyst with the activity toward the dissociation of methanol and water is very desirable to facilitate the commercialization of DMFC. The transition metal carbides have been shown to exhibit catalytic properties similar to Pt-Group metals in reactions with hydrocarbon molecules. This work is to determine the feasibility of using WCs as an alternative anode catalyst. This work began by synthesizing and characterizing the PVD WC thin films, in order to bridge the materials gap between previous model crystal surfaces and the more realistic electrocatalysts. Fundamental surface science techniques where applied to examine the composition of the film. Ex situ cyclic voltammetry (CV) measurements have been applied to examine the electrocatalyst stability of the thin films. Supported WCs synthesized by temperature programmed reaction (TPR) technique was also used as a bridge material with a larger surface area than PVD thin films. Supported WC samples were also tested by surface science techniques. CV measurements were performed to examine the electrocatalyst stability and methanol oxidation in an electrochemical environment. In ex situ CV study, the solution is very complicated for deciding the activity of WC towards methanol oxidation. A gas phase reaction, cyclohexene self-hydrogenation as a probe reaction for WC reactivity was performed in a batch reactor with IR, in order to evaluate the dehydrogenation activity of WC and Pt-modified WC.

Direct Alcohol Fuel Cells: Materials, Performance, Durability and Applications begins with an introductory overview of direct alcohol fuel cells (DAFC); it focuses on the main goals and challenges in the areas of materials development, performance, and commercialization. The preparation and the properties of the anodic catalysts used for the oxidation of methanol, higher alcohols, and alcohol tolerant cathodes are then described. The membranes used as proton conductors in DAFC are examined, as well as alkaline membranes, focusing on the electrical conductivity and alcohol permeability. The use of different kinds of carbon materials as catalyst supports, gas diffusion layers, and current collectors in DAFC is also discussed. State of the art of the modeling is used to estimate performance and durability. The closing chapter reviews the use of DAFC in portable equipment and mobile devices and features a detailed discussion on the mechanisms of component degradation which limits their durability. This book is written to facilitate the understanding of DAFC technology, applications, and future challenges.
