... for use in a hybrid SOFC-gas turbine (GT) system. A numerical fuel cell model is developed based on charge, species mass, energy, and momentum balances, and an equivalent circuit is used to combine the fuel cell's irreversibilities. The model is then verified on electrochemical, mass, and thermal...

... at the moment of the simulation, the highest fuel utilization was limited to be 60%. In this scenario, the total power output of the system is the sum of the power output from the fuel cell stack and the gas turbine hardware subsystem, P total  =  P FC   +   P GT . The power offset due to degradation...
