    摘要： A fuel cell system includes a fuel supply unit for supplying fuel, an air supply unit for supplying air, a coolant supply unit for supplying coolant, and a stack having an electricity generator in which separators are disposed on both surfaces of a membrane-electrode assembly so as to generate electric energy through an electrochemical reaction between hydrogen and oxygen supplied from the fuel supply unit and the air supply unit. The stack includes a plurality of cooling channels through which a coolant is supplied from the coolant supply unit. The cooling channels include contact-area extension surfaces for increasing the contact area of the coolant in order to provide improved cooling efficiency.
