AI Technical Summary

Technical Problem

The existing proton exchange membrane fuel cell system cannot effectively utilize hydrogen at low electrical density points, resulting in the hydrogen induction device being unable to perform an induction effect and the system consumes a high power consumption.

Method used

Design a hydrogen supply system, combines a hydrogen circulation pump and a hydrogen induction device, and starts the hydrogen circulation pump at a low electric tight point to solve the problem that the hydrogen induction device cannot play a induced induction device; turn off the hydrogen circulation pump at a medium and high electric tight point and only use the hydrogen induction device to reduce the power consumption of the system BOP.

Benefits of technology

The fuel cell system effectively utilizes hydrogen at low electric density points, improves hydrogen utilization and reduces system power consumption.

Abstract

The invention relates to the technical field of proton exchange membrane fuel cell detection, and particularly provides a proton exchange membrane fuel cell hydrogen supply system test method and system, the system comprises a hydrogen supply tool, the output end of the hydrogen supply tool is connected with a rotor flow meter 1, the rotor flow meter 1 is connected to the inlet of a hydrogen ejector assembly, and the rotor flow meter 2 is connected to the outlet of the hydrogen ejector assembly. The hydrogen supply system is simple and convenient to design, easy to install and operate and simple and convenient to operate, and has the advantages of a hydrogen circulating pump and a hydrogen ejector, the hydrogen circulating pump is started by the fuel cell system at a low current density point, and the fuel cell system is started by the hydrogen ejector at a low current density point. The problem that the hydrogen ejector cannot play an ejection role at a low current density point is solved, the hydrogen circulating pump is closed at a medium-high current density point, only the hydrogen ejector is used, the power consumption of a system BOP is reduced, the power consumption of a fuel cell system is reduced, and the hydrogen utilization rate is improved.
