Fuel Cells: Principles, Design, and Analysis considers the latest ad¬
vances in fuel celt system development and deployment and was written
with engineering and science students in mind. This book provides readers
with the fundamentals of fuel cell operation and design and incorporates
techniques and methods designed to analyze different fuel cell systems. It
builds on three mam themes: basic principles, analysis, and design.
The section on basic principles contains background information on fuel
cells, including fundamental principles such as electrochemistry, thermo¬
dynamics, and kinetics of fuel cell reactions as well as mass and heat
transfer in fuel cells. The section on design explores important characteris¬
tics associated with various fuel cell components, electrodes, electrocata-
lysts, and electrolytes, while the section on analysis examines phenomena
characterization and modeling both at the component and system levels.
•
Includes objectives and a summary in each chapter
•
Presents examples and problems demonstrating
theory/principle applications
•
Provides case studies on fuel cell analysis
•
Contains mathematical methods including numerical
methods and
MATLAB Simutink
techniques
•
Offers references and material for further reading
Fuel Cells:
Principies,
Design, and Analysis presents the basic prin¬
ciples, examples, and models essential in the design and optimization of
fuel ceil systems. Based on more than ten years of the authors teaching
experience, this text is an idea! resource for junior- to senior-level under¬
graduate students and for graduate students pursuing advanced fuel cell
research and study.
