A cogeneration system using fuel cells is provided to withdraw heat energy from waste heat generated from the generation system through a simplified route. A cogeneration system using fuel cells includes: a steam-generating unit(10) which withdraws reactants and waste heat discharged from a reformer(1) and a fuel cell stack(3) and generates steam using the reactants and waste heat; a generation unit(21,22) which generates electric energy using steam generated from the steam-generating unit; a condenser(30) which withdraws steam discharged from the generation unit and subjects the steam to low-pressure expansion; and a pressurization unit(50) which applies pressure to working fluid supplied from the condenser, and sends back the working fluid to the steam-generating unit. |
