Abstract

Ever-increasing energy consumption, raising public awareness for environmental protection, and higher prices of fossil fuels have motivated many to look for renewable energy sources. SOFC is one of the best alternative energy sources, but it is a highly nonlinear system. In this paper, isothermal and non-isothermal models of solid oxide fuel cell have been developed under the general condition of unchoked outlet flow. For the isothermal dynamic model of SOFC, linear and gain scheduling controllers have been designed for voltage control. Since pressure control in SOFC stack plays a significant role, a controller developed based on full-state feedback linearization and provided a comparison with a linear controller.
