Polymer Membranes for Fuel Cells by Javaid Zaidi,Takeshi Matsuura Pdf

From the late-1960’s, perfluorosulfonic acid (PFSAs) ionomers have dominated the PEM fuel cell industry as the membrane material of choice. The “gold standard’ amongst the many variations that exist today has been, and to a great extent still is, DuPont’s Nafion® family of materials. However, there is significant concern in the industry that these materials will not meet the cost, performance, and durability requirementsnecessary to drive commercialization in key market segments – es- cially automotive. Indeed, Honda has already put fuel cell vehicles in the hands of real end users that have home-grown fuel cell stack technology incorporating hydrocarbon-based ionomers. “Polymer Membranes in Fuel Cells” takes an in-depth look at the new chem- tries and membrane technologies that have been developed over the years to address the concerns associated with the materials currently in use. Unlike the PFSAs, which were originally developed for the chlor-alkali industry, the more recent hydrocarbon and composite materials have been developed to meet the specific requirements of PEM Fuel Cells. Having said this, most of the work has been based on derivatives of known polymers, such as poly(ether-ether ketones), to ensure that the critical requirement of low cost is met. More aggressive operational requi- ments have also spurred the development on new materials; for example, the need for operation at higher temperature under low relative humidity has spawned the creation of a plethora of new polymers with potential application in PEM Fuel Cells.

Proton Exchange Membrane Fuel Cells by David P. Wilkinson,Jiujun Zhang,Rob Hui,Jeffrey Fergus,Xianguo Li Pdf

A Detailed, Up-to-Date Treatment of Key Developments in PEMFC Materials The potential to revolutionize the way we power our world Because of its lower temperature and special polymer electrolyte membrane, the proton exchange membrane fuel cell (PEMFC) is well-suited for transportation, portable, and micro fuel cell applications. But the performance of these fuel cells critically depends on the materials used for the various cell components. Durability, water management, and reducing catalyst poisoning are important factors when selecting PEMFC materials. Written by international PEMFC scientists and engineers from top-level organizations, Proton Exchange Membrane Fuel Cells: Materials Properties and Performance provides a single resource of information for understanding how to select and develop materials for improved PEMFC performance. The book focuses on the major components of the fuel cell unit, along with design and modeling aspects. It covers catalysts and catalyst layers, before discussing the key components of membranes, diffusion layers, and bipolar plates. The book also explores materials modeling for the PEMFC. This volume assesses the current status of PEMFC fuel cell technology, research and development directions, and the scientific and engineering challenges facing the fuel cell community. It demonstrates how the production of a commercially viable PEMFC requires a compromise of materials with adequate properties, design interaction, and manufacturability.

Proton Exchange Membrane Fuel Cells by Hui Li,Shanna Knights,Zheng Shi,John W. Van Zee,Jiujun Zhang Pdf

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.

Proton Exchange Membrane Fuel Cells Modeling by Fengge Gao,Benjamin Blunier,Abdellatif Miraoui Pdf

The fuel cell is a potential candidate for energy storage and conversion in our future energy mix. It is able to directly convert the chemical energy stored in fuel (e.g. hydrogen) into electricity, without undergoing different intermediary conversion steps. In the field of mobile and stationary applications, it is considered to be one of the future energy solutions. Among the different fuel cell types, the proton exchange membrane (PEM) fuel cell has shown great potential in mobile applications, due to its low operating temperature, solid-state electrolyte and compactness. This book presents a detailed state of art of PEM fuel cell modeling, with very detailed physical phenomena equations in different physical domains. Examples and a fully coupled multi-physical 1.2 kW PEMFC model are given help the reader better understand how to use the equations.
