摘要： An apparatus and a method for controlling a humidification amount of a membrane humidifier for a fuel cell are provided. The humidification amount of the membrane humidifier relative to air supplied to a stack is changed by adjusting a difference in partial pressure of moisture between the inside and the exterior of a hollow fiber membrane that constitutes the membrane humidifier for a fuel cell.

摘要： The invention relates to a method for operating a fuel cell system during a heating phase or another transient operating phase or a method for adjusting a relative humidity of a cathode operating gas. The fuel cell system comprises a fuel cell stack with anode and cathode chambers separated by polymer electrolyte membranes, and a cathode supply for supplying and discharging the cathode operating gas into and out of the cathode chambers, as well as a cooling system for controlling the temperature of the fuel cell stack. The method has the following steps: determining an inlet temperature of the cathode operating gas at the inlet of the fuel cell stack, setting a coolant setpoint temperature at the inlet of the fuel cell stack to a value which is equal to or less by a predetermined amount than the inlet temperature of the cathode operating gas, and controlling the cooling system so that a coolant temperature prevailing at the inlet of the fuel cell stack at least approximates the coolant setpoint temperature.

摘要： Systems and methods for initiating voltage recovery procedures in a fuel cell system based in part on an estimated specific activity over the life of a fuel cell catalyst are presented. In certain embodiments, SA loss of catalyst and electrochemical surface area loss of a FC system may be estimated. An output voltage of the FC system may be estimated based on the estimated SA loss and the electrochemical surface area loss. An amount of recoverable voltage loss may be determined based on a comparison between the estimated output voltage and a measured output voltage. Based on the determined amount of recordable voltage loss, a FC system control action (e.g., a voltage recovery procedure) may be initiated.

摘要： A fuel cell control method includes calculating an amount of water in a humidifier using a production amount of water at a cathode of a fuel cell, a discharge amount of saturated vapor and a discharge amount of water at an anode, judging whether or not a vehicle is in a driving state using state information of the vehicle, judging humidity of air in the fuel cell stack upon judging that the vehicle is in the driving state, increasing RPM of an air blower and activating the air blower when the amount of water is greater than a first threshold and a second condition is satisfied, if first conditions are satisfied, and activating a heater when the amount of water is greater than a second threshold, if the first conditions are not satisfied.

摘要： A fuel cell control method includes detecting a state value indicating a state in a fuel cell during an operation of the fuel cell. The fuel cell includes a membrane electrode assembly and a separator stacked on the membrane electrode assembly. The membrane electrode assembly includes a solid polymer electrolyte membrane sandwiched between an anode electrode and a cathode electrode. It is determined whether a liquid connects the solid polymer electrolyte membrane and the separator based on the state value detected. The fuel cell is dried in a case where it is determined that the liquid connects the solid polymer electrolyte membrane and the separator.

摘要： The present invention is to provide, in a combined system of a bioethanol producing device and an SOFC, a method that is capable of further enhancing the electric power generation efficiency of the SOFC, and is also capable of achieving further reduction of the energy required for distillation of the fermented liquid. A part of an anode off-gas is refluxed to the water-containing ethanol vapor line from the mash column to the reforming device at a reflux ratio ((flow rate of reflux gas)/(flow rate of (anode off-gas)−(reflux gas))) of from 1 to 2. The ethanol concentration of the water-containing ethanol vapor is controlled by refluxing, to a range of from 25 to 35% by weight with water contained in the anode off-gas of the solid oxide fuel cell.
