Abstract

The invention discloses a gas-electricity system, a control method of the gas-electricity system and a vehicle, and belongs to the technical field of vehicles. According to the gas-electricity system, an air path is communicated with a cathode inlet of a fuel cell stack assembly, an air compressor is arranged on the air path, and an outlet of the air compressor is communicated with the input end of a hydrogen compression pump device; the output end of the hydrogen compression pump device can be communicated with a hydrogen path; the hydrogen path is communicated with an anode inlet of the fuel cell stack assembly; and the first end of the hydrogen recovery path is communicated with the anode outlet of the fuel cell stack assembly, and the second end of the hydrogen recovery path can be communicated with the hydrogen compression pump device. The gas-electricity system, the control method of the gas-electricity system and the vehicle are low in cost and simple in structure, and the danger of hydrogen leakage explosion caused by electric sparks does not exist.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a fuel-electric system, a method for controlling the fuel-electric system, and a vehicle. Background technique [0002] With the increasingly severe global environmental and energy issues, fuel cell vehicles are considered to be the most promising energy power devices in the future because of their advantages such as no pollution, high energy conversion efficiency, and wide source of raw materials. [0003] The design scheme of PEMFC (proton exchange membrane fuel cell, proton exchange membrane fuel cell) hydrogen supply system is divided into hydrogen recycling and non-hydrogen recycling. The non-hydrogen recycling requires high fuel cell performance, which is not conducive to the high-efficiency use of anode fuel. As well as the service life of the fuel cell system, hydrogen recycling can use hydrogen with high efficiency and is conducive to stack maintenance and management. ...
