Abstract

A dynamic model for a solid oxide fuel cell power plant has been constructed. The concept of a feasible operating area for a solid oxide fuel-cell power plant is introduced by establishing the relationship between the stack terminal voltage, fuel utilization, and stack current. By controlling the input hydrogen fuel in proportion to the stack current, constant utilization control can be accomplished. The effectiveness of the proposed schemes is illustrated through simulation.
