A power distribution system comprises at least one fuel cell that is selectively operated in response to conditions to provide power to electrical loads and/or to charge an electrical storage device such as a vehicle battery. One form of an alternator can be selectively engaged or disengaged to provide power to the electrical loads and/or to charge the electrical storage device. Either or both of the fuel cell and alternator can be operated to provide electrical power.

Adjustable aerodynamic devices are controlled to control the drag on a vehicle. In one form, control is accomplished in response to pressure from a plurality of pressure sensors. In another form, control is accomplished in response to air movement measurements, such as of wind speed and direction at a location that a vehicle has yet to reach. In another form, the position and location of air vortices between a cab and trailer can be determined and adjusted to adjust the drag by controlling aerodynamic devices.
