Effect of Non-Uniform Inlet Flow Rate on the Preheating Process of a Solid Oxide Fuel Cell Unit

Abstract

This study simulates the preheating process of a solid oxide fuel cell unit with the cross-flow configuration, and investigates the effect of the non-uniform inlet flow pattern and the non-uniform deviation on the maximum temperature gradient and preheating time. The numerical method is accuracy and reliable through the comparison with the analytical solution of previous literature. The results show that the effect of non-uniform inlet flow pattern on the maximum temperature gradient is obvious, and the effect in the fuel side is more obvious than that in the airside. The best choice of the inlet flow pattern is C, which the fuel side is uniform and the airside is the progressively increasing profile. Additionally, the effect of non-uniform inlet flow pattern on the preheating time is slight, but the effect of non-uniform deviation on the preheating time should be considered.
