The system is advantaged in that purposes of high efficiency, cleanness and no pollution are achieved, the instantaneous power is high, thesystem cost is greatly reduced, and the service life of the galvanic pile is prolonged.

Description

[technical field] [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to an integrated self-charging storage battery system in which hydrogen fuel cells are used as chargers. [Background technique] [0002] Because hydrogen fuel cells have the advantages of no pollution, low noise, high efficiency, etc., their application range is becoming wider and wider. A hydrogen fuel cell system generally consists of a hydrogen fuel cell stack (referred to as a stack), an auxiliary battery, a DC / DC (direct current-direct current) converter, and a stack management system. Among them, the electric stack is the core of the hydrogen fuel cell system, which makes the hydrogen and the oxygen in the air react electrochemically to generate electricity, and at the same time generate water to discharge; the auxiliary battery provides the initial power for the start-up of the electric stack management system; the DC / DC converter starts to voltage conversion a...
