Dynamic Simulation of Plate-Type Reformer and Combustor System for Molten Carbonate Fuel Cell

摘要

In this study, a plate-type reformer for MCFC has been designed and analyzed. Also, a control system using MPC has been applied to provide a stable hydrogen source to fuel cell. The plate-type reformer is configured the reformer and combustor in alternating manner to maximize the heat transfer between the reformer and combustor. The models for plate-type reformers and combustors have been developed in a PDE form and the effects of the important manipulated variables on the crucial output variables have been investigated. From the simulations, it is found that the interactions between variables are significant and an efficient control system is required. Thus, the MPC is designed to control the H_2 production rate and the reformer temperature by manipulating the reformer feed and the combustor fuel flow rates.
