Abstract

This work presents an advanced computational fluid dynamics (CFD) model of a 5 kW molten carbonate fuel cell (MCFC) stack intended to provide a broad analysis and deliver improved design through optimizing flow distribution. The goal is to provide a variant analysis of flow distribution in the internal channels through the CFD model. SolidWorks was used to design the MCFC stack, and SOLIDWORKS ® Flow Simulation was utilized to model the flow distribution inside the stack. The simulated stack was validated through an experimental investigation of a 5 kW MCFC stack, empirically measuring pressure and flow distribution in an experimental laboratory station optimized for multi-scale fuel cell stack testing. The test was designed to examine a variety of internal flow distribution factors. The verified CFD model was employed for sensitivity analysis on various scales. To enhance the design, the influence of stack and single-cell constructional characteristics on the 5 kW MCFC was investigated.
