POWER SUPPLY SYSTEM FOR FUEL CELL AND FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/020098
Kind Code:
A1
Abstract:
A power supply system for a fuel cell, comprising a fuel cell stack, a 24VDC/DC converter and a fuel cell controller; a high voltage input end of the 24VDC/DC converter is connected to the fuel cell stack; a low voltage output end of the 24VDC/DC converter is connected to a low-voltage busbar of the fuel cell; and the low-voltage busbar of the fuel cell is electrically connected to the fuel cell controller and a storage battery for a fuel cell. The power supply system has the advantage of eliminating as much as possible the impact of voltage fluctuation on the power supply of the fuel cell controller and electrical accessories of a fuel cell system; and when 24VDC/DC suddenly fails, the storage battery for a fuel cell can be used for supplying power, thereby guaranteeing the safety of the fuel cell system. The present invention further relates to a fuel cell system.
