  • Methods of operating fuel cell stacks and systems related thereto
    Patent number: 8962206
    Abstract: Methods and systems for operating a fuel cell stack having a fuel exhaust stream and a vessel downstream of the fuel cell stack fluidly connected to the fuel exhaust stream are provided. In one embodiment, the method comprises displacing substantially all residual gas in the vessel by providing at least a portion of the fuel exhaust stream to the vessel, and isolating the vessel from the fuel cell stack after the fuel exhaust stream displaces substantially all residual gas in the vessel. At least one bleed down characteristic is determined as fuel exhaust within the vessel is released through an orifice, and an operating condition of the fuel cell stack is set or determined based on the at least one bleed down characteristic. In a specific embodiment, the hydrogen concentration in the fuel exhaust is determined based on the at least one bleed down characteristic.

  • METHOD FOR OPERATING A FUEL CELL STACK FOR A FUEL CELL SYSTEM, AND FUEL CELL SYSTEM
    Publication number: 20150044590
    Abstract: A method for operating a fuel cell stack (10) for a fuel cell system, in particular of a vehicle, in which by reversing the flow direction (14, 16) of a coolant during a cooling operation, the coolant in the fuel cell stack (10) is initially conveyed in a first direction (14). The coolant is subsequently conveyed in a second direction (16) which is at least substantially opposite to the first direction (14). A time period, after the elapse of which the flow direction (14, 16) is reversed, is changed during the cooling operation. In addition, a distance at which a coolant volume is situated from a heat source (12) that is present in the fuel cell stack (10) may be changed during the cooling operation. The invention further relates to a fuel cell system.
