Experiental study on the dynamic characteristics of kW-scale molten carbonate fuel cell systems

摘要

The aim of this work is to develop dynamic models for two types of kW-scale molten carbonate fuel cell (MCFC) systems on the basis of experimental data. The dynamic models are represented as a 3 x3 transfer function matrix for a multi-input and multi-output (MIMO) system with three inputs and three outputs. The three controlled variables which severely affect the stack performance and lifetime are the temperature difference in the stack and the pressure drop at the anode and the cathode.
