A supply device for supplying electricity to at least one consumer includes: a primary power supply in which there is a first fuel cell device having a first performance; a voltage transformer which connects the primary power supply to a secondary power supply having a battery; and a measuring device for detecting an insulation resistance of the primary power supply and/or of the secondary power supply. A second fuel cell device having a second performance is connected in series with the first fuel cell device in the primary power supply, wherein a bridge circuit comprising a switch is connected in parallel with each of the fuel cell devices and wherein the switches of the bridge circuits can be switched in accordance with the detected insulation resistance. A fuel cell vehicle and a method for limiting voltage in a supply device are also provided.
