The book provides a systematic and profound account of scientific challenges in fuel cell research. The introductory chapters bring readers up to date on the urgency and implications of the global energy challenge, the prospects of electrochemical energy conversion technologies, and the thermodynamic and electrochemical principles underlying the op
Analytical Modelling of Fuel Cells, Second Edition, is devoted to the analytical models that help us understand the mechanisms of cell operation. The book contains equations for the rapid evaluation of various aspects of fuel cell performance, including cell potential, rate of electrochemical reactions, rate of transport processes in the cell, and temperature fields in the cell, etc. Furthermore, the book discusses how to develop simple physics-based analytical models. A new chapter is devoted to analytical models of PEM fuel cell impedance, a technique that exhibits explosive growth potential. Finally, the book contains Maple worksheets implementing some of the models discussed. - Includes simple physics-based equations for the fuel cell polarization curve - Provides analytical solutions for fuel cell impedance - Includes simple equations for calculation of temperature shapes in fuel cells - Introduces physical descriptions of the basic transport and kinetic phenomena in fuel cells of various types
In fuel cell research, the gap between fundamental electrochemical processes and the engineering of fuel cell systems is bridged by the physical modelling of fuel cells. This relatively new discipline aims to understand the basic transport and kinetic phenomena in a real cell and stack environment, paving the way for improved design and performance. The author brings his unique approach to the analytical modeling of fuel cells to this essential reference for energy technologists. - Covers recent advances and analytical solutions to a range of problems faced by energy technologists, from catalyst layer performance to thermal stability - Provides detailed graphs, charts and other tools (glossary, index) to maximize R&D output while minimizing costs and time spent on dead-end research - Presents Kulikovsky's signature approach (and the data to support it)—which uses "simplified" models based on idealized systems, basic geometries, and minimal assumptions—enabling qualitative understanding of the causes and effects of phenomena
When one great author engages another, as Andrei Bely so brilliantly does in Gogol’s Artistry, the result is inevitably a telling portrait of both writers. So it is in Gogol’s Artistry. Translated into English for the first time, this idiosyncratic, exhaustive critical study is as interesting for what it tells us about Bely’s thought and method as it is for its insights into the oeuvre of his literary predecessor. Bely’s argument in this book is that Gogol’s earlier writing should be given more consideration than most critics have granted. Employing what might be called a scientific perspective, Bely considers how often certain colors appear; he diagrams sentences and discusses Gogol’s prose in terms of mathematical equations. The result, as strange and engaging as Bely’s best fiction, is also an innovative, thorough, and remarkably revealing work of criticism.
