Thermodynamic Optimization of a Monolithic-Type Solid Oxide Fuel Cell*

摘要: In the presented paper possible design modifications in tubular solid oxide fuel cell (SOFC) geometry are investigated order to increase its performance. The analysis of entropy generation mechanism is very important optimize second-law performance these energy conversion devices. use this technique makes it identify main irreversibilities, understand their causes and propose changes system operation. various contributions analyzed separately which geometrical parameters be considered as independent variables optimization procedure. applied a CFD model accounts for equation, fluid dynamics channels porous media, current transfer, chemical reactions, electrochemistry raditive heat transfer. computed post-processed quantity with data obtained model. modified minimize overall generation. Boundary conditions provided aid reduced thermal take account stack operating condition.
