Abstract
Heat exchangers and pre-reformers are critical devices for high temperature fuel cell systems. It is recommended to incorporate a compact heat exchange and the pre-reformer when considering the limited space and cost. The volume-resistance characteristic modeling technique is introduced here to meet the requirement for quick dynamic and real time simulations. The distribution characteristics along the heat exchange reformer length direction are presented, and some key effect factors are studied. The transient behaviors are investigated for different step-change conditions, such as mass flow rate and inlet temperature. This can provide some references and tools for the fuel cell system design and optimization.
