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 filling a fuel cell anode supply manifold with hydrogen prior to a start-up operation to facilitate a substantially even hydrogen distribution across the fuel cell is disclosed. The anode supply manifold is in fluid communication with a source of hydrogen. A first valve in fluid communication with the anode supply manifold and a second valve in fluid communication with an anode exhaust manifold are initially in a closed position while hydrogen is supplied to the anode inlet conduit to pressurize the fuel cell stack. The first valve is then opened to purge at least a portion of a fluid from the anode supply manifold to facilitate a filling of the manifold with hydrogen.

摘要： A method for monitoring the pressure in an anode sub-system of a fuel cell system during a pressurization stage at system start-up prior to an anode purge. The method includes providing hydrogen gas to the anode sub-system during the pressurization stage, typically from one or more injectors. The method determines how many moles of the hydrogen gas has been provided to the anode sub-system, and uses the number of moles to determine the pressure in the anode sub-system. The method uses the determined pressure to stop the pressurization stage when the determined pressure is about equal to the desired pressure.

摘要： The present invention relates to controlled staged rich combustion throughout a fuel processing system in order to improve start up performance. Multiple stages of air injection are used to burn rich combustion products within each component to provide direct heating thereof. During the start up cycle, the fluid temperature entering each reactor is increased and each component is heated to its operating temperature in parallel. The controlled staged rich combustion eliminates the load imposed upon a combustor within the system during the start up cycle. Thus, each of the components within the fuel processing system may be optimized for an operational mode rather than a start up mode.

摘要： A method for reducing the probability of an air/hydrogen front in a fuel cell stack is disclosed that includes closing anode valves for an anode side of the fuel cell stack to permit a desired quantity of hydrogen to be left in the anode side upon shutdown and determining a schedule to inject hydrogen during the time the fuel cell stack is shutdown. The pressure on an anode input line is determined and a discrete amount of hydrogen is injected into the anode side of the stack according to the determined schedule by opening anode input line valves based on the determined pressure along the anode input line so as to inject the hydrogen into the anode side of the stack.

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 system. The method also includes determining a volumetric flow rate through a cathode compressor, determining a volumetric flow rate through the stack cathode and determining a fraction of volumetric flow rate through the cathode 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. The method uses a desired fraction of volumetric flow rate through the cathode and the total flow through the compressor to determine the position of the by-pass valve.

摘要： Processes to shut down a fuel cell system are described. In one implementation (400), fuel (H2) and oxidizer (air) flow is halted and the system's anode region (305) is sealed. A load (215) is then engaged across the system's fuel cell stack (205) so as to deplete much of the fuel in the stack's sealed anode region (305). The stack (205) is monitored to determine when the load should be disengaged. (215). Once the load is disengaged, fluid communication between the system's anode and cathode regions is established. The vacuum created in the anode region (305) as a consequence of consuming H2 therein, pulls nitrogen enriched gas from the cathode region (310) into the anode region (305). When substantially all of the H2 has been depleted from the anode region (305), no pressure difference exists between the anode and cathode regions and fluid communication between the two is severed.
