This book lays out a numerical framework for the detailed description of heterogeneous chemistry, electrochemistry and porous media transport in solid-oxide fuel cells (SOFC). Assuming hydrogen as the only electrochemically active species, a modified Butler-Volmer equation is used to model the electrochemical charge transfer.

Thisv olume contains four chapters. The topics covered are solid state electrochemistry devices and techniques; nanoporous carbon and its electrochemical application to electrode materials for super capacitors; the analysis of variance and covariance in electro chemical science and engineering; and the last chapter presents the use of graphs in electrochemical reaction networks. Chapter 1 by Joachim Maier continues the solid state electrochemistrydi scussiont hat hebeg an in Volume 39 of the Modern Aspects of Electrochemistry. He begins by introducing the reader to the major electrochemical parameters needed for the treatmentof electroch emical cells. In section 2 he discusses various sensors: electrochemical (composition), bulk conductivity, surface conductivity, galvanic. He also discusses electrochemical energy storage and conversion devices such as fuel cells. GyoungJ a Lee and SuIl P yun in chapter two review the synthesis and characterization of nanoporous carbons and their electrochemical application to electrode material for super capacitors in relationship to the key role nanoporous carbons havepla yed, for example, in the purification of liquids and carbons, catalytic reaction, and the storage of energy. Activation and templating methods are discussed in section II. They survey the structural characteristics of the porous carbons by the use the gas adsorption method in Section III. Section IV discusses the molecular probe method and the image analysis method for quantitative characterization of the pore surface irregularity and the size distribution irregularity based on the fractal theory.
