Fuel cell systems(FCSs) have potential to achieve a financial and environmental advantage over competing technologies. For use in residences and buildings FCSs can provide useful heating/hot water and electricity generation at a high overall efficiency. In this study, a 1.5Kw-class Polymer electrolyte fuel cell system(PEFCS) with a battery pack has been modelled and simulated. Its electric conversion efficiency and heat recovery performance are highly dependent on the seasonal thermal and electric load of a residence. Seasonal average fuel saving rates are calculated to find proper load management methods. The scheme can be used to determine the optimal capacity and operating strategies of PEFCS.
