specific Embodiment

[0029] refer to Figure 1-4 , a specific embodiment of the present invention is proposed, a method for controlling an air compressor of a fuel cell system, comprising the following steps:

[0030] S10. Obtain real-time rotational speed data and air flow data of the air compressor.

[0031] S30. Determine whether the real-time air flow data and rotational speed data are within a preset surge data range.

[0032] S40. If it is within the range, increase the output air flow rate of the air compressor.

[0033] For step S10, the real-time speed data and air flow data of the air compressor are obtained, and the working state of the air compressor is judged based on the speed data and air flow data, and whether the current working state of the air compressor is a normal working state or a surge state .

[0034] The specific step S10 includes step S11, obtaining the real-time air flow data of the air compressor through the air flow meter.

[0035] For step S11, the air flow meter...

Abstract

The invention discloses a control system of an air compressor of a fuel battery system. The method comprises the steps of acquiring real-time rotating speed data of the air compressor and air flow rate data; determining whether the real-time air flow rate data and the rotating speed data are within a preset surging data range; and if so, increasing the output air flow rate of the air compressor. The method has the beneficial effects that the real-time rotating speed data and the flow rate data are acquired while the air compressor runs, and that the air compressor is in a surging state can bedetermined based on the acquired data, and thus the problem of surging of the air compressor can be solved by increasing the output air flow rate of the air compressor; the method is direct and efficient; and the air compressor is prevented from secondary damage.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a control method for an air compressor of a fuel cell system. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; Transmission parts, so there is no noise, and the harmful gas emitted is very little; sound pollution. [0003] The main trend in the development of new energy vehicles is the diversification of vehicle energy and the electrification of vehicle power. As a high-efficiency, zero-pollution vehicle power supply, fuel cells are an ideal cho...
