Abstract: 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.

Abstract: A system for measuring the insulation resistance of a fuel cell vehicle is provided. The system includes a fuel cell that supplies power, a rechargeable high-voltage battery, and a bidirectional converter, disposed between an output terminal of the fuel cell and the high-voltage battery, to adjust a voltage at the output terminal of the fuel cell. A fast measurement unit measures the insulation resistance of the fuel cell vehicle by being connected to the output terminal of the fuel cell and a second measurement unit measures the insulation resistance of the fuel cell vehicle by being connected to the output terminal of the high-voltage battery. A controller operates the bidirectional converter based on the state of the fuel cell vehicle and measure the insulation resistance of the fuel cell vehicle using the first measurement unit or the second measurement unit

Abstract: A power distribution method and system for a fuel cell vehicle is provided. The method includes deducing an amount of moisture in a stack of a fuel cell, when a supply amount of air of the stack of the fuel cell is decreased and determining a state of the fuel cell based on the amount of moisture. Additionally, the method includes deducing allowance power of a regenerative braking of a driving motor using maximum power of the regenerative braking of an air compressor and chargeable power of a high voltage battery based on the determined state. The regenerative braking of the driving motor is then adjusted to prevent actual power of the regenerative braking of the driving motor from exceeding the allowance power of the regenerative braking.
