Abstract
Process for electrically energizing a motor vehicle wiring circuit which has a battery, at least one electric consuming device and a fuel cell unit connected therein. The fuel cell unit is activated when the battery voltage falls below a preadjustable battery voltage limit, and when the wiring load exceeds a preadjustable vehicle wiring load; and is deactivated when the battery voltage exceeds a preadjustable battery voltage limit.
