Large-scale commercialization of proton exchange membrane fuel cell (PEMFC) technology has been hindered by issues of reliability, durability, and cost, which are all related to the degradation of fuel cell performance. This degradation often has root causes in contamination from fuel, air streams, or system components. With contributions from international scientists and engineers active in PEMFC research, Proton Exchange Membrane Fuel Cells: Contamination and Mitigation Strategies discusses the impacts of contamination and the contamination mitigation strategies to improve fuel cell performance and durability. The book covers the nature, sources, and electrochemistry of contaminants; their effects on fuel cell performance and lifetime; and the mechanisms of contamination. Exploring the major findings from experimental and theoretical studies in contamination-related research, the expert contributors present methods and tools used for diagnosing various contamination phenomena, along with strategies for mitigating the adverse effects of contamination. They also describe key issues in the future R&D of fuel cell contamination and control. Helping to facilitate pioneering PEMFC R&D and accelerate sustainable commercialization, this book contains the latest research efforts and novel developments as well as important new directions in PEMFC contamination. It offers a comprehensive overview of nearly every aspect of fuel cell contamination, from fundamentals to applications.

MATLAB is a useful tool for computer specialists. Economists also should be assisted by computer specialists or benefit from computer software package. However, computer specialists can not solve complicated economic problems because of the lack of in-depth of understanding of economics. This book aims to provide technical reference for the regional economists and the regional economy workers to master MATLAB. Conceptual framework for regional economic decision-making problems is presented in the book, and MATLAB-based solutions and technical details. It is possible to get through the regional economy, the concept and the technology gap between fuzzy mathematics and MATLAB. The book is to try to make a regional economist master MATLAB tools in a relaxed atmosphere. Therefore, it simplifies off all unnecessary programming content. Meanwhile, in order to enable the reader to the creative application of MATLAB, the book discusses the main aspects of the actual problems of the regional economic decisions, which will help regional economists improve their projects based on the application of MATLAB.
