Steady-state and transient analysis of a steam reformer based Solid Oxide Fuel Cell system.

Steady-state and transient analysis of a steam reformer based Solid Oxide Fuel Cell system. - 53 p.

Thesis (M.S.)--Michigan State University, 2008.

In this thesis we perform a model-based analysis of a Solid Oxide Fuel Cell (SOFC) system with an integrated steam reformer and with methane as fuel. The objective of this study is to analyze the steady-state and transient characteristics of this system for varying current demand. For the analysis, we develop a control-oriented model of the system that captures the heat and mass transfer, chemical kinetics and electro-chemical phenomena. We express the dynamics of the reformer and the fuel cell in state-space form. By applying coordinate transformations to the state-space model, we derive analytical expressions of steady-state conditions and transient behaviors of two critical performance variables, namely utilization and steam-to-carbon balance. Using these results, we solve a constrained fuel optimization problem in steady-state using linear programming. Our analysis is supported by simulations. The results presented in this thesis can be applied in predicting transient response and will be useful in control development for SOFC systems.
