Since the fuel cell system has high configuration and safety requirements for the test site, it is urgent to provide a simple and safe fuel cell system container test device.

[0003] Traditionally, hydrogen fuel cell testing is usually carried out in a hydrogen fuel cell engine laboratory. In this testing environment, the fuel cell itself and the experimenter are in the same space. Once a dangerous situation occurs, there is a major safety hazard for the experimenter.

[0004] Moreover, when the fuel cell is being tested, hydrogen, oxygen, air and other fluids need to be introduced into the fuel cell system, which places high demands on the exhaust, ventilation and drainage of the experimental environment. Setting up a mechanism that matches the above functions in the laboratory environment is difficult and expensive for laboratory renovation.

[0005] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0006] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a containerized fuel cell system testing device which has a simple structure, ingenious design, reasonable layout, can effectively eliminate potential safety hazards, has a relatively high integration level and is low in cost.

[0007] The technical solution of the utility model is: a container-type fuel cell system test device, characterized in that: the device comprises a container box body 1, the inner cavity of the box body 1 is divided into a monitoring area 3 and a test area 4 by a protective wall 2, and an explosion-proof window 5 is arranged on the protective wall 2.

[0008] An air purifier 6 and two explosion-proof cameras 7 located in diagonal directions are arranged on the ceiling in the test area 4. A hydrogen pipeline 8 and a nitrogen pipeline 9 are also arranged in the test area 4. A hydrogen hose 10 is connected to the hydrogen pipeline 8. A first hydrogen valve 11 is arranged at the connection position between the hydrogen hose 10 and the hydrogen pipeline 8. A nitrogen hose 12 is connected to the nitrogen pipeline 9. A first nitrogen valve 13 is arranged at the connection position between the nitrogen hose 12 and the nitrogen pipeline 9.

Traditionally, the test of the fuel cell system is carried out in a laboratory environment, and the operator and the fuel cell are in the same space, so there is a great safety hazard. In response to the above problems, the present application creatively sets the pipelines, lines and related instruments for the fuel cell system test in a container-type box, and at the same time sets a protective wall in the box to separate the fuel cell to be tested from the operator. The operator only needs to observe in the monitoring area (through the explosion-proof window or the picture collected by the camera) to know the test situation of the fuel cell. At the same time, it integrates the pipelines and equipment required for various tests, which is sufficient to meet the test requirements of the fuel cell system. In addition, the manufacturing process of this device is simple and the manufacturing cost is low, so it can be said that it has many advantages, and is particularly suitable for promotion and application in this field, and its market prospects are very broad.
