FUEL CELL SYSTEM

摘要

PURPOSE: Provided is a fuel cell system, by which hydrogen can be supplied stably without using a reformer, the fuel can be exchanged with ease to constitute a portable fuel cell system, and the energy loss can be prevented. CONSTITUTION: The fuel cell system comprises: a fuel cell stack part(110) comprising an electrolyte membrane and a fuel pole(113) and an air pole(114) disposed on the both sides of the electrolyte membrane to generate the electricity by the electrochemical reaction between the fuel and air; a fuel supplying part(120) comprising a fuel tank(121) containing a liquid fuel, a fuel cycling duct(122) for connecting the fuel tank to the fuel pole(113) in a cycling mode, and a fuel pump(123) disposed in the middle of the fuel cycling duct(122) for pumping the fuel toward the fuel pole(113); an air supplying part(130) comprising an air compressor, and an air supplying duct connected to the air compressor for guiding the air to the air pole(114); an air humidifying part(140) comprising a humidifier(141) disposed in the middle of the air supplying duct for moistening air, a water supplying duct(143) connected to the humidifier(141) for supplying water needed to the humidifier(141), and a water pump disposed in the middle of the water supplying duct(143) for pumping water in a water source toward the humidifier(141); and an electric energy output part(160) for supplying the electric energy generated in the fuel cell stack part(110) to the load.
