Title: Fuel cell system
Inventor: AOYAMA SATOSHI
IPC: H01M8/04
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To increase a ratio of a water vapor contained in a raw gas including a hydrocarbon fuel, oxygen and the water vapor and to supply the amount of water vapor meeting the hydrocarbon fuel to a reformer. SOLUTION: In this system, a gas mixed with an exhaust gas from a cathode and the air and a methane from a methane tank 60 are brought into contact with a hot water of a humidifier 50 to be moisturized for supplying a reformer 22. An exhaust gas from an anode is fired by a combustor 52 to heat the hot water of the humidifier 50 and the pressure of the humidifier 50 is adjusted by an adjustment valve 72. A saturated water vapor pressure in a raw gas is determined by temperature or pressure and the ratio of the water vapor in the raw gas in the saturated water vapor pressure to the methane is determined by a partial pressure of the methane in the raw gas. Thus the raw gas is included with the exhaust gas of the cathode to adjust the partial pressure of the methane and adjusting the temperature and pressure of the humidifier 50 adjusts the saturated water vapor pressure.  Consequently, the ratio of the water vapor in the raw gas to the methane.
