Abstract: An anode poison reduction system and method for a fuel cell vehicle. The system includes a monitoring device configured to monitor a state and performance of a fuel cell, and a controller configured to perform first control of controlling output of the fuel cell or air supply when an anode poisoning possibility condition is satisfied as a monitoring result by the monitoring device, and configured to perform second control of supplying air in the air line to the anode through the connection line when an anode poisoning generation condition is satisfied.

Abstract: The present disclosure relates to an apparatus and a method for controlling a concentration of exhaust hydrogen in a fuel cell system. The apparatus may include an air exhaust valve for discharging hydrogen from a cathode in a fuel cell stack to an outside environment through an air exhaust line, an air compressor for supplying ambient air to the air exhaust line, an air cut-off valve for blocking air supplied to the cathode, and a controller that opens the air exhaust valve and drives the air compressor when starting to supply hydrogen to the fuel cell stack, and opens the air cut-off valve such that a concentration of the hydrogen discharged from the cathode is reduced by air in the air exhaust line when the hydrogen supply is completed.

Abstract: A hydrogen supply method for a fuel cell system, for supplying hydrogen according to a state of the fuel cell system when the fuel cell system is started, includes steps of (a) measuring a stop time period which elapses until the fuel cell system is started after the fuel cell system is stopped, (b) determining whether a reaction time period consumed to complete a reaction of residual hydrogen and residual oxygen residing in a fuel cell stack since the fuel system is stopped is not more than the stop time period, and (c) when it is determined in the step (b) that the stop time period is less than the reaction time period, closing a purge valve that is able to discharge gases accommodated in an anode from the anode and supplying at the same time hydrogen to the anode such that an internal pressure of the anode becomes a predetermined first target pressure.

Abstract: A fuel cell system includes a fuel cell stack having a cathode and an anode, a humidifier configured to humidify air that is to be supplied to the cathode, an air supply unit configured to supply the air to the humidifier, and a controller. The controller is configured to adjust a flow rate of the air supplied from the air supply unit, based on a supply of the humidifier, to prevent flooding of the fuel cell stack.
