摘要： An FCV includes: a driving device that generates traveling power by using at least one of FC energy and battery energy; and a display device that presents an indicator indicating the traveling power that is being generated by the driving device. When the traveling power is less than a threshold value, the driving device generates the traveling power by using one energy of the FC energy and the battery energy without using the other energy of the FC energy and the battery energy. When the traveling power is more than or equal to the threshold value, the driving device generates the traveling power by using both the FC energy and the battery energy. At the indicator, the display device presents information indicating the threshold value.

摘要： A power supply device for the electric power supply of at least one consumer is provided having a primary power grid, in which there is present a fuel cell arrangement comprising electric contacts, which includes a discharge circuit switched in parallel and connected to the electric contacts, comprising a switch element activatable by means of a controller across a switch line as well as a resistance element, and having a DC-DC converter which is present in the primary power grid, by which the primary power grid is connected to a secondary power grid, characterized in that the discharge circuit comprises a safety device or a safety function, which holds the switch element in an opened state and thereby makes the discharge circuit inactive for as long as an actuating possibility exists via the switch line, and which places the switch element in a closed state and thereby makes the discharge circuit active for lowering the voltage of the fuel cell arrangement once the actuating possibility via the switch line is denied. Furthermore, a method for lowering the voltage of a fuel cell arrangement of a power supply device is also provided.
