Abstract: A vehicle includes an electric motor, a fuel cell, and a fuel cell thermal management system. A control system of the vehicle is configured to operate the fuel cell and the fuel cell thermal management system according to different modes. The modes include an acoustic signature mode in which an acoustic signature of the vehicle is reduced, a thermal signature mode in which a thermal signature of the vehicle is reduced, an acoustic and thermal signature mode in which both the acoustic signature and the thermal signature of the vehicle are reduced, a mission mode in which the vehicle is a node of a mesh network of other vehicles, and an optimized efficiency mode in which the fuel cell and the fuel cell thermal management system are controlled based on ambient conditions.

Abstract: Fuel cell systems aboard means of transport can be used for generating energy and for producing water. In order to reduce the overall weight of the system, the fuel cell is controlled or regulated in dependence on a current fill level or a limit level of the water tank, as well as a predicted future water consumption. In this way, it may be possible to minimize the water quantity to be stored in the water tank.

Abstract: Methods and apparatus are provided for a fuel cell including a fuel desulfurization system. The fuel cell system includes a source of fuel and a fuel desulfurization system fluidly coupled to the source of fuel to receive the fuel in a liquid phase. The fuel desulfurization system includes a vacuum system that depressurizes the fuel to convert at least a portion of the fuel from the liquid phase to a gaseous phase. The fuel cell system also includes a fuel cell stack fluidly coupled to the fuel desulfurization system to receive fuel from the fuel desulfurization system in the gaseous phase.

Abstract: A fuel cell system includes a control unit that detects an abnormality of a flow dividing valve provided in a bypass channel for an oxidation gas by using a detected opening degree detected by a valve opening degree detection sensor that detects the opening degree of the flow dividing valve. When the detected abnormality is an opening abnormality that is failure to open and the flow dividing valve can close, the control unit sends a closing command for making the opening degree smaller than a current opening degree to a valve driving motor. Either when the detected abnormality is a closing abnormality that is failure to close and the flow dividing valve can open or when the detected abnormality is an opening-closing abnormality that is failure both to close and to open, the control unit sends a maintaining command for maintaining the opening degree to the valve driving motor.
