This book is an ensemble of six major chapters, an introduction, and a closure on modeling transport phenomena in porous media with applications. Two of the six chapters explain the underlying theories, whereas the rest focus on new applications. Porous media transport is essentially a multi-scale process. Accordingly, the related theory described in the second and third chapters covers both continuum‐ and meso‐scale phenomena. Examining the continuum formulation imparts rigor to the empirical porous media models, while the mesoscopic model focuses on the physical processes within the pores. Porous media models are discussed in the context of a few important engineering applications. These include biomedical problems, gas hydrate reservoirs, regenerators, and fuel cells. The discussion reveals the strengths and weaknesses of existing models as well as future research directions.

Polymer Electrolyte Membrane (PEM) fuel cells convert chemical energy in hydrogen into electrical energy with water as the only by-product. Thus, PEM fuel cells hold great promise to reduce both pollutant emissions and dependency on fossil fuels, especially for transportation—passenger cars, utility vehicles, and buses—and small-scale stationary and portable power generators. But one of the greatest challenges to realizing the high efficiency and zero emissions potential of PEM fuel cells technology is heat and water management. This book provides an introduction to the essential concepts for effective thermal and water management in PEM fuel cells and an assessment on the current status of fundamental research in this field. The book offers you: • An overview of current energy and environmental challenges and their imperatives for the development of renewable energy resources, including discussion of the role of PEM fuel cells in addressing these issues; • Reviews of basic principles pertaining to PEM fuel cells, including thermodynamics, electrochemical reaction kinetics, flow, heat and mass transfer; and • Descriptions and discussions of water transport and management within a PEM fuel cell, including vapor- and liquid-phase water removal from the electrodes, the effects of two-phase flow, and solid water or ice dynamics and removal, particularly the specialized case of starting a PEM fuel cell at sub-freezing temperatures (cold start) and the various processes related to ice formation.

Direct Liquid Fuel Cells is a comprehensive overview of the fundamentals and specificities of the use of methanol, ethanol, glycerol, formic acid and formate, dimethyl ether, borohydride, hydrazine and other promising liquid fuels in fuel cells. Each chapter covers a different liquid fuel-based fuel cell such as: Anode catalysts of direct methanol fuel cells (DMFCs), future system designs and future trends for direct ethanol fuel cells (DEFCs), development of catalysts for direct glycerol fuel cells (DGFCs), the mechanisms of the reactions taking place at the anode and cathode electrodes, and the reported anode catalysts for direct formic acid fuel cell (DFAFC) and direct formate fuel cell (DFFC), characteristics of direct dimethyl ether fuel cell (DDMEFC), including its electrochemical and operating systems and design, the developments in direct borohydride fuel cells, the development of catalysts for direct hydrazine fuel cells (DHFCs), and also the uncommonly used liquids that have a potential for fuel cell applications including 2-propanol, ethylene glycol, ascorbic acid and ascorbate studied in the literature as well as utilization of some blended fuels. In each part, the most recent literature is reviewed and the state of the art is presented. It also includes examples of practical problems with solutions and a summarized comparison of performance, advantages, and limitations of each type of fuel cell discussed. Direct Liquid Fuel Cells is not a typical textbook but rather designed as a reference book of which any level of students (undergraduate or graduate), instructors, field specialists, industry and general audience, who benefit from current and complete understanding of the many aspects involved in the development and operation of these types of fuel cells, could make use of any chapter when necessary. Presents information on different types of direct liquid fuel cells. Explores information under each section, for specific fuel-based fuel cells in more detail in terms of the materials used. Covers three main sections: direct alcohol, organic fuel-based and inorganic fuel-based fuel cells

This volume contains an archival record of the NATO Advanced Institute on Mini – Micro Fuel Cells – Fundamental and Applications held in Çesme – Izmir, Turkey, July 22–August 3, 2007. The ASIs are intended to be a high-level teaching activity in scientific and technical areas of current concern. In this volume, the reader may find interesting chapters on Mini- Micro Fuel Cells with fundamentals and applications. In recent years, fu- cell development, modeling and performance analysis has received much attention due to their potential for distributed power which is a critical issue for energy security and the environmental protection. Small fuel cells for portable applications are important for the security. The portable devices (many electronic and wireless) operated by fuel cells for providing all-day power, are very valuable for the security, for defense and in the war against terrorism. Many companies in NATO and non-NATO countries have concentrated to promote the fuel cell industry. Many universities with industrial partners committed to the idea of working together to develop fuel cells. As tech- logy advanced in the 1980s and beyond, many government organizations joined in spending money on fuel-cell research. In recent years, interest in using fuel cells to power portable electronic devices and other small equipment (cell phones, mobile phones, lab-tops, they are used as micro power source in biological applications) has increased partly due to the promise of fuel cells having higher energy density.
