摘要： A fuel cell system including a humidification system is described. The humidification system employs a recycling system that recycles relatively humid gas exhausted from a multistage fuel cell stack, either on the anode and/or cathode side, and sends this relatively humid gas back to be combined with relatively dry supply gas, such as but not limited to hydrogen and/or air. The humidified supply gas mixture is then reintroduced into the first stage of the multistage fuel cell stack. A recirculation device, such as but not limited to a pump and/or an ejector, can be used to aid in moving the humid exhaust gas back through a recycle gas line to be combined with the supply gas.

摘要： A fuel cell system that employs an injector/ejector for providing fresh hydrogen and anode recirculation gas to the anode side of a fuel cell stack. The injector/ejector is operated with a variable frequency so that the injector open time at low stack current densities is long enough to allow a pressure drop to be provided in the anode flow channels to push out water that may have accumulated therein. In one embodiment, the injector/ejector control provides a minimum pulse width per cycle and a maximum frequency so that as the stack current density decreases below a certain value the frequency decreases from the maximum frequency to maintain the pulse width constant at the minimum pulse width.

摘要： A fuel cell system wherein a plurality of fuel cells are arranged in a series of stages, the number of fuel cells decreasing in number in each stage from anode gas inlet to the anode gas outlet. The system allows for parallel flow to all of the cells in a given stage and series flow between the various stages. A similar configuration is present on a cathode side of the system. However, the direction of flow is reversed, providing a greater number of cells in the stage nearest the cathode outlet and a fewer number of cells in the stage near the cathode gas inlet. The invention further provides for the various stages to be configured such that the direction of flow of the anode gas of a given stage is generally opposite the direction of flow of the cathode gas of a given stage.

摘要： A fuel cell system that determines the phase transition from water to gas through a bleed/drain valve in a water separation device. The fuel cell system includes a fuel cell stack having an anode side and a cathode side. An injector injects hydrogen gas into the anode side of the fuel cell stack. The water separation device receives an anode exhaust gas from the anode side of the fuel cell stack, where the water separation device includes a water holding reservoir. A controller controls the injector and the bleed/drain valve and determines when the bleed/drain valve transitions from draining water to bleeding the anode exhaust gas by comparing the flow rate through the water separation device and the flow rate through the injector.
