Problems solved by technology

The normal operation of the monitoring system can only be ensured by the good connection between each single cell of the fuel cell group and the inspection system, otherwise false detection will be carried out, which will affect the normal operation of the fuel cell
At present, it is generally used to drill holes on the bipolar plates of each section of the battery pack, install metal needles, and set the inspection line on the metal needles for detection. However, due to vibration or repeated use, the inspection line and the metal needles will be loose and in poor contact. An error signal occurs (or a loose connection between the metal pin and the bipolar plate causes an error signal), which affects the normal operation of the battery pack
[0003] At present, there are no documents and patents related to the connection method of better fuel cell inspection lines

Embodiment 1

[0019] Application of fuel cell quick-plug inspection interface in fixed test platform: assemble a 50kW fuel cell stack with 180 cells. Use the 20-channel line row 3 and the multi-channel D-type connector element 1 to press into a 20-channel quick-plug inspection interface element, and connect the other end of the multiple quick-plug inspection interface element lines to the fuel cell bipolar Plates (including collector plates) are welded together in sequence. Place the battery pack with quick-plug inspection interface components on the fuel cell test platform to connect the pipelines and lines; then connect the fuel cell quick-plug inspection interface with the quick-plug inspection Check the interface for plugging. Various performance tests of fuel cells are carried out. The test shows that using this method to connect the fuel cell group and the detection system, there is no phenomenon that the inspection line falls off during battery operation, the connection between the...

Embodiment 2

[0021] Application of quick-plug inspection interface in dynamic fuel cell performance test: Two 50kW fuel cell stacks (180 cells / set) using this connection method are assembled into a fuel cell power generation system with a net output of 60kW as The engine of the 863 fuel cell city bus. The 863 project team headed by Tsinghua University conducted a 3,000-kilometer actual running performance test on this fuel cell city bus. During the test, there was never any bad contact between the inspection line and the battery pack, which laid the foundation for the stable operation of the fuel cell engine. good foundation. At the same time, because the inspection line is connected to the fuel cell detection system by quick plug (the battery pack can be quickly disconnected and connected to the inspection system), it provides great convenience for the maintenance of the fuel cell engine.

Abstract

The invention relates to the field of fuel cell, concretely a fast-inserting method for connecting fuel battery patrol lines, pressing a multichannel D-type socket connector and a bus together, composing a fast inserting patrol interface, welding the other end of the bus on one side of dipolar plate of the fuel battery; making the other fast inserting patrol interface by the same means, and connecting the bus with a fuel cell testing system; socketing the fast-inserting patrol interfaces on the fuel battery and on the patrol system together for making real time detection on the fuel cells. The invention simplifies the connection operating procedure of the fuel battery and the patrol system, and the connection is firm and simple and short-cut.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a method for connecting inspection lines of quick-insert fuel cell groups. Background technique [0002] With the development of the global economy, energy crisis and environmental pollution have become the main problems in the world today. A fuel cell is a high-efficiency power generation device that directly converts the chemical energy in fuel and oxidant into electrical energy. A fuel cell is a high-efficiency, energy-saving, and environmentally friendly power generation device due to its environmental protection and future petroleum energy substitutes. The fuel cell business has been widely valued by the governments, business circles and academic circles of various countries. The US Department of Energy regards the fuel cell project as a pool of national key development projects. The Ministry of Science and Technology of my country launched the 863 major electric vehicle project i...
