A hybrid system consisting of a solid oxide fuel cell, a semiconductor thermoelectric generator and a regenerator is put forward. Expressions for the efficiencies and power outputs of the fuel cell, thermoelectric generator and hybrid system are derived. The relation between the electric currents in the fuel cell and thermoelectric generator is revealed. The maximum efficiency and power output of the hybrid system are calculated numerically. The optimally operating electric currents in the fuel cell and thermoelectric generator are calculated and consequently the optimal region of the hybrid system is determined. The results obtained here will provide some guidance for further understanding the performance and operation of practical fuel cell–thermoelectric generator hybrid systems.
