Ideas And Methods Exchange Series

This book contains revised versions of papers presented on scientific workshop “Modeling Multi-commodity Trade: Information exchange methods”, which took place in November 2010 atWarsaw University of Technology. It summarizes results of the research work supported so far by scientific grant “Methods and architectures of information interchange for electronic trade on infrastructural markets” (see page xi), and some earlier research work on multi-commodity markets modeling. Though partial results of the research were published earlier, the book gives the most complete view on results of our research in the field of modeling the trade on complex multi-commodity infrastructural markets.

Water and Thermal Management of Proton Exchange Membrane Fuel Cells introduces the main research methods and latest advances in the water and thermal management of PEMFCs. The book introduces the transport mechanism of each component, including modeling methods at different scales, along with practical exercises. Topics include PEMFC fundamentals, working principles and transport mechanisms, characterization tests and diagnostic analysis, the simulation of multiphase transport and electrode kinetics, cell-scale modeling, stack-scale modeling, and system-scale modeling. This volume offers a practical handbook for researchers, students and engineers in the fields of proton exchange membrane fuel cells. Proton exchange membrane fuel cells (PEMFCs) are high-efficiency and low-emission electrochemical energy conversion devices. Inside the PEMFC complex, physical and chemical processes take place, such as electrochemical reaction, multiphase flow and heat transfer. This book explores these topics, and more. Introduces the transport mechanism for each component of PEMFCs Presents modeling methods at different scales, including component, cell, stack and system scales Provides exercises in PEMFC modeling, along with examples of necessary codes Covers the latest advances in PEMFCs in a convenient and structured manner Offers a solution to researchers, students and engineers working on proton exchange membrane fuel cells
