A fuel cell system is provided to allow a heat distribution unit to be supplied with deficient heat from the heat supply source of a fuel supply unit even without an auxiliary heat supply part, thereby simplifying the entire constitution and improving heating efficiency. A fuel cell system comprises a stack unit(110) which generates electricity by the electrochemical reaction of air and hydrogen; an air supply unit(120) which supplies to the stack unit; a fuel supply unit(130) which supplies hydrogen to the stack unit; and a heat distribution unit(140) which is supplied with heat from the heat supply source of the fuel supply unit to provide warm water or heating. Preferably the heat distribution unit comprises a water tank(141) which stores the water supplied to the heat exchange part(136) of the fuel supply unit and the stack unit; a heating line(143) where the water heated at the heat exchange part circulates; a heat exchanger(144) which exchanges heat between the water flowing the heating line and the water stored at the water tank; and a warm water line(142) which provides the water of the water tank heat exchanged at the heat exchanger as warm water. |
