摘要
Abstract
A three-dimensional mathematical model considering fluid flow, heat transfer, charge transfer, species transport and electrochemical reaction in solid oxide fuel cell was developed. The studied domain consists of fluid channels, electrolyte,diffusion layers and activation layers of cathodes and anodes. The transport phenomena which occurred in the whole solid oxide fuel cell is described by the generalized equation, in which different parameters and source terms are employed for different layers. The flow characteristics, distributions of temperatures and pressures, and component concentrations in 3-D space are obtained by solving the transport equation set coupled with the electrochemical kinetics equations. The general differential equations are solved by computation fluid dynamics technique. A comparison of predicted performance and experimental data in literature was made to validate the mathematical model.关键词
