An Active and Reactive Power Analysis of Solid Oxide Fuel Cell

Abstract

This paper presents an active and reactive power analysis of Solid Oxide Fuel Cell (SOFC) model. This model is developed from electrochemical and thermal equations. It accounts for temperature-dynamics, ohmic loss, concentration loss, activation loss and output-voltage loss. The relaxation time is strongly related to the transient temperature distribution of the solid oxide fuel cell structure. The proposed model contains the hydrogen, oxygen and water block separately to increase the active power. The analytical detail of active and reactive power output of a stand-alone SOFC power plant is controlled by fuzzy logic. This model is validated through Matlab program under transient behavior. A comparative assignment of PI and Fuzzy – Logic controller is carried out for SOFC power plant model
