Abstract:
An arrangement for an interruption-free energy supply to an electrical consumer, comprising:an a.c. voltage network,a protone exchange membrane fuel cell;a switch which connects the electrical consumer to said a.c. voltage network when the network voltage of said a.c. voltage network lies above a threshold value and disconnects the electrical consumer from said a.c. voltage network when the network voltage of said a.c. voltage network lies below said threshold value; andan inverted rectifier connected to said fuel cell and to said switch, wherein:said fuel cell is maintained in a standby mode when the network voltage of said a.c. voltage network lies above said threshold value, andsaid fuel cell takes over the energy supply to the electrical consumer within a few milliseconds when the network voltage of said a.c. voltage network drops below said threshold value.
