    摘要: A fuel cell stack antifreeze system that purges a plurality of fuel cell stacks connected in parallel includes a compressor that supplies pressurized cathode gas to each of the plurality of fuel cell stacks. A controller deactivates a first group of one or more of the plurality of fuel cell stacks and maintains operation of a second group of one or more of the plurality of fuel cell stacks. The second group powers the compressor and the compressor purges excess fluid from the first group using the pressurized cathode gas.

    摘要: A temperature control scheme for a fuel cell stack thermal sub-system in a fuel cell system. The thermal sub-system includes a coolant loop directing the cooling fluid through the stack, a pump for pumping the cooling fluid through the coolant loop, a radiator for cooling the cooling fluid outside of the fuel cell stack and a bypass valve for selectively directing the cooling fluid in the coolant loop through the radiator or around the radiator. The control scheme generates an optimal model of the thermal sub-system using non-linear equations, and controls the speed of the pump and a position of the bypass valve in combination.

    摘要: A temperature control scheme for a fuel cell stack thermal sub-system in a fuel cell system that uses a non-linear thermal model and disturbance rejection to provide an optimum stack temperature. The thermal sub-system includes a coolant loop directing a cooling fluid through the stack, a pump for pumping the cooling fluid through the coolant loop, and a radiator for cooling the cooling fluid outside of the fuel cell stack. The system includes a controller for controlling the speed of the pump so as to maintain the temperature of the stack at a desired temperature. The controller uses the thermal model to anticipate a temperature of the cooling fluid out of the fuel cell stack to control the speed of the pump.

    摘要: A temperature control system and method for a fuel cell stack cooling system is disclosed. The temperature control system includes a coolant circulation line for circulating a coolant to and from a fuel cell stack. A coolant pump is provided in the coolant circulation line, and a pump ΔP sensor is provided in fluid communication with the coolant circulation line on inlet and outlet sides of the coolant pump. The pump ΔP sensor measures a change in pump pressure between the inlet and outlet sides of the coolant pump. A pump map is provided having correlated values of pump speed, change in pump pressure and coolant flow rate for correlating the coolant flow rate with the pump speed and the change in pump pressure to attain a desired coolant flow rate for optimum fuel stack cooling.

    摘要: A method and apparatus of operating a compressor of a fuel cell system includes modeling a flow meter that measures a mass flow from a compressor with a first mathematical formula and generating a measured signal from the flow meter. The first mathematical formula and the measured signal are processed through a recursive Kalman filter based signal processing algorithm to provide a future signal estimate. The compressor is operated based on the future signal estimate.
