| Abstract: | A numerical model of a 10 kW class co-flow MCFC stack was established based on mass, momentum, and energy conservation equations. Boundary conditions were also presented. The corrugated plate of the MCFC stack is taken into consideration. Then the model was solved for gas pressure and temperature in each part. A model of electricity generation characteristics was given and solved. The performance in the gas flow direction was analyzed in detail. The dynamic characteristics of the stack as the current density changes were investigated using dynamic simulation. The effectiveness of the MCFC stack model was demonstrated by the experimental data. |
