摘要： An electrochemical fuel cell assembly (1) includes a fuel cell stack (2) having a fuel delivery inlet (3) and a fuel delivery outlet. The fuel cell has a membrane-electrode assembly and a fluid flow path coupled between the fuel delivery inlet and the fuel delivery outlet for delivery of fuel to the membrane-electrode assembly. A fuel delivery conduit (6) is coupled to the fuel delivery inlet (3) for delivery of fluid fuel to the fuel cell stack (2). A flow control device (11) in the fluid delivery conduit (6) is configured to provide a pulse modulated inlet pressure at the fuel delivery inlet (3). The pulse modulation may be provided as a function of fuel cell operating conditions. The amplitude and frequency of the pulse modulation may be selected to create sufficient flow disturbance to encourage disturbance and dislodgement of water collecting in the fluid flow path.

摘要： Aspects of methods and systems to reduce degradation of a fuel cell (110) during start-up and shut-down cycles are disclosed. An anode exhaust stream (201') is periodically directed via fluid communication through an oxygen capture media (86). After shut-down of the fuel cell and before or during start-up said media (86) removes oxygen in the anode exhaust stream. Periodically, heating the oxygen capture media (86) is employed to purge the oxygen collected and regenerate the media.

摘要： The present disclosure provides methods for turbine-based energy recovery from exhaust streams in fuel cell systems. The fuel cell systems can include an expansion turbine (200) arranged to capture electrical energy from cathode exhaust streams. The cathode exhaust streams (151a, 151b, 151c) can be flowed through an intercooler (250) to be preheated prior to entering the expansion turbine (200), with heat added by transferring heat from a compressed air flow. The methods can include operating the fuel cell system in a temperature-boost mode that includes reducing fan operation related to a condenser to reduce liquid recapture from an exhaust stream and increase exhaust stream temperature for use in turbine-based energy recovery. The temperature-boost mode can be controlled to limit the operation time based on coolant fluid levels in the fuel cell system.

摘要： A fuel cell controller 10 for controlling the operation of a fuel cell system (1, fig 1) comprises a plurality of fuel cells (2, fig 1) arranged together to provide electrical current at an output (7, fig 1), the controller being configured to actively set an upper limit 20 on the rate of change in current provided by the fuel cell system at the output based on at least one electrical parameter of one or more of the fuel cells of the fuel cell system. The electrical parameter is preferably voltage, and may comprise at least two separate voltage parameters 21, 22. For example, the controller 10 may be configured to receive at 21 a live measure of the mean cell voltage of two or more of the plurality of fuel cells (2, fig 1) and at 22 a live measure of a minimum cell voltage comprising a voltage of a fuel cell within the fuel cell system that has the lowest voltage of the plurality of fuel cells. The spread or reverse spread voltage measurement of fuel cells within the fuel cell system may also be used. The fuel cell system, a method of controlling the fuel cell system and a computer program for executing the method are also claimed.

摘要： An electrochemical fuel cell assembly comprises a fuel cell stack having a fuel delivery inlet and a fuel delivery outlet. The fuel cell stack further includes a number of fuel cells each having a membrane-electrode assembly and a fluid flow path coupled between the fuel delivery inlet and the fuel delivery outlet for delivery of fuel to the membrane- electrode assembly. A fuel delivery conduit is coupled to the fuel delivery inlet for delivery of fluid fuel to the stack. A bleed conduit is coupled to the fuel delivery outlet for venting fluid out of the stack. A variable orifice flow control device coupled to the bleed conduit configured to dynamically vary an amount of fluid from the fuel delivery outlet passing into the bleed conduit as a function of one or more of the control parameters: (i) measured fuel concentration; (ii) measured humidity; (iii) cell voltages of fuel cells in the stack; (iv) impedance of fuel cells in the stack; (v) resistance of fuel cells in the stack. The variable orifice flow control device may be coupled to a recirculation conduit and may be configured to dynamically vary a proportion of fluid from the fuel delivery outlet passing into the bleed conduit as a function of the control parameters.
