This work presents an advanced CFD model of a 10kW Molten Carbonate Fuel Cell stack intended to provide a broad analysis and design improvement through the flow distribution optimization. The goal is to improve the MCFC's constructional characteristics and single-cell design. SolidWorks was used to design the MCFC stack, and SOLIDWORKS® Flow Simulation was used to model the flow distribution inside the stack. The simulated stack was validated on the experimental investigation of a 5kW MCFC stack with an average error of 5%. The pressure and flow distribution in the tested MCFC stack were investigated experimentally in a laboratory experimental station optimized for multi-scale fuel cell stacks testing. The test was designed to examine a variety of internal flow distribution factors. For sensitivity analysis on various scales, the verified CFD model was employed. The influence of stack and single-cell constructional characteristics on the 10 kW MCFC were investigated and used to enhance the design.
