Abstract

The invention provides a vehicle-mounted fuel cell hybrid power system. The hybrid power system comprises at least one power supply unit and at least one control unit, wherein the control unit is arranged to be capable of controlling the power supply unit to supply power to a vehicle electric load. According to the vehicle-mounted fuel cell hybrid power system, the response to the electricity demand of the electricity load of the vehicle can be improved, and the conversion rate of fuel can be increased.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a vehicle-mounted fuel cell hybrid power system. The present invention further relates to a power supply method for a vehicle-mounted fuel cell hybrid power system. Background technique [0002] A fuel cell is a power generation device that converts chemical energy in fuel directly into electrical energy through electrochemical reactions. The electrical reaction process of fuel cells does not involve combustion, so its energy conversion efficiency is not limited by the Carnot cycle, and has the advantages of high efficiency and cleanliness. Secondly, the refueling time of the fuel cell is short, and it does not need to be charged for as long as a conventional electric vehicle, making it more convenient to use. Furthermore, fuel cells, especially proton membrane exchange fuel cells, utilize hydrogen as fuel. Hydrogen has a high energy density, and accordingly, the fuel cell ...
