  • Publication number: 20230307675
    Abstract: A fuel cell generation system control apparatus performs a method for controlling power of a fuel cell generation system. A monitoring device monitors power of the one or more fuel cell modules. A controller compensates for power of one or more first fuel cell modules by one or more second fuel cell modules, based on the monitored power, and performs power control of the one or more fuel cell modules. The fuel cell generation system control apparatus addresses a problem in which power of the fuel cell generation system is reduced as there is a change in external environment or an increase in driving time upon power control of a multi-module fuel cell system.

  • Patent number: 11515551
    Abstract: A fuel cell recovery control system and method are provided to supply hydrogen to the cathode of a fuel cell stack to remove an oxide film formed on a platinum surface of the cathode. The performance of the fuel cell stack is recovered in accordance with the oxide film removal. In addition, electric power generated during the performance recovery of the fuel cell stack is consumed in an inverter and, as such, overcharge of a battery is prevented.

  • Patent number: 11489183
    Abstract: A fuel cell system includes a fuel cell stack including fuel and air electrodes, a fuel gas supply module configured to supply hydrogen and oxygen, as fuel gases, to the fuel cell stack, a fuel gas supply line including channels through which the fuel gases are supplied to the fuel cell stack, a humidification module disposed in the fuel gas supply line and configured to supply moisture to the fuel gases, and a controller configured to control the fuel gas supply line such that the fuel gases bypass the humidification module and are directly supplied to the fuel cell stack when temperature of the fuel cell stack is determined low at an initial stage of operation of the fuel cell stack, and the fuel gases pass through the humidification module and are supplied to the fuel cell stack when the temperature reaches a normal temperature.

  • Patent number: 11309560
    Abstract: A method of predicting a life of a membrane electrode assembly (MEA) of a fuel cell for electric power generation includes: deriving an operating condition for accelerated degradation, which is applicable to the fuel cell; operating the fuel cell for a specific time under the derived operating condition for accelerated degradation and under a normal operating condition, and identifying the degree of degradation of the fuel cell under each of the operating conditions; calculating an acceleration multiple based on the degree of degradation identified under the operating condition for accelerated degradation and under the normal operating condition; and predicting the life of the membrane electrode assembly based on the acceleration multiple.
