Entropy Generation Minimization

The aim of the paper is to investigate possible design modifications in tubular solid oxide fuel cell geometry to increase its performance. The analysis of the cell performances is conducted on the basis of the entropy generation. The use of this technique makes it possible to identify the phenomena provoking the main irreversibilities, understand their causes and propose changes in the system design and operation. The different contributions to the entropy generation are analyzed in order to develop new geometries that increase the fuel cell efficiency. To achieve this purpose, a CFD model of the cell is used. The model includes energy equation, fluid dynamics in the channels and in porous media, current transfer, chemical reactions, and electrochemistry. The geometrical parameters of the fuel cell are modified to minimize the overall entropy generation.

In this article, a combined heat and power (CHP) system using a solid oxide fuel cell and mini gas turbine is introduced. Since a fuel cell is the main power generating source in hybrid systems, in this investigation, complete electrochemical and thermal calculations in the fuel cell are carried out in order to obtain more accurate results. An examination of the hybrid system performance indicates that increasing of the working pressure and rate of air flow into the system, cause the cell temperature to reduce, the efficiency and the power generated by the system to diminish, and the entropy generation rate and exergy destruction rate to increase. On the other hand, increasing the flow rate of the incoming fuel, the rise in cell temperature causes the efficiency, generated power, and exergy destruction rate of the system to increase.
