Abstract
A system and method are provided for controlling a plurality of fuel cells. The method includes coordinating a distribution of a power demand in response to a power request of a power system comprising a plurality of fuel cells, the power output of each of the fuel cells selected based on a respective efficiency of each of the fuel cells.
Claims20
A method, comprising:
- coordinating, by a controller, a distribution of a power demand for a power output in response to a power request of a power system comprising a plurality of fuel cells, the power output of each of the fuel cells selected based on a respective efficiency of each of the fuel cells;
- and
- propelling a vehicle system by the power output of each of the fuel cells.
A system, comprising:
- a power system comprising a plurality of fuel cells, with each of the fuel cells having an efficiency range;
- and
- a controller that is configured to coordinate a distribution of a power demand for a power output of the power system in response to a power request, the power output of each of the fuel cells selected based on a respective efficiency of each of the fuel cells.
A vehicle, comprising:
- one or more electric traction motors;
- a fuel cell system electrically coupled to the electric traction motors, and the fuel cell system comprising a plurality of fuel cells;
- and
- a controller that is configured with executable instructions stored on non-transitory memory that, when executed, cause the controller to individually operate the fuel cells at a determined efficiency setting to meet a power demand and to activate fuel cells sequentially until the power demand has been met, and the determined efficiency is set to be greater than 90 percent efficient in converting fuel to electricity.
