摘要： A method for controlling cathode air flow at system start-up by controlling a stack by-pass valve. The method includes determining a concentration of hydrogen in a cathode side of the fuel cell stack. The method also includes determining a volumetric flow rate through a cathode compressor, determining a volumetric flow rate through the cathode side and determining a fraction of volumetric flow rate through the cathode side to the total flow through the compressor. The method determines a modeled hydrogen outlet concentration from the fuel cell stack based on the volumetric flow rate through the compressor, the fraction of volumetric flow rate through the compressor to the total flow through the compressor and the concentration of hydrogen in the cathode side. The method uses a desired fraction of volumetric flow rate through the cathode side and the total flow through the compressor to determine the position of the by-pass valve.

摘要： A method for determining when to inject hydrogen gas into the anode side of a fuel cell stack associated with a fuel cell vehicle when the vehicle is off. The method includes estimating the concentration of hydrogen gas in the anode side of the fuel cell stack using a gas concentration model and determining if the estimated concentration of hydrogen gas is below a first predetermined threshold. If the estimated hydrogen gas is less than the threshold, then hydrogen gas is injected into the anode side from a hydrogen source. While the hydrogen gas is being injected, the method compares the estimated concentration of the hydrogen gas in the anode side to a desired concentration, and generates an error signal there between. If the error signal is greater than a second predetermined threshold, the algorithm continues to inject the hydrogen into the anode side of the fuel cell stack.

摘要： A system and method for detecting small hydrogen leaks in an anode of a fuel cell system. The method includes determining that a shut-down sequence has begun, and if so, deplete the cathode side of a fuel cell stack of oxygen. The method then increases the pressure of the anode side of the fuel cell stack to a predetermined set-point, and monitors the pressure decay of the anode side of the stack. The method compares the rate of pressure decay to an expected pressure decay rate, and if the measured pressure decay rate exceeds the expected pressure decay rate by a certain threshold, determines that a potential leak exists.
