Problems solved by technology

[0002] In the traditional fuel cell testing process, there are the following defects: 1) the electric energy generated by the tested fuel cell system is lost through heat consumption, resulting in a waste of resources and an increase in cost
When the hydrogen in the hydrogen cylinder is used up, the system will stop running, causing the test to be interrupted
However, the fuel cell test system runs for a long time and consumes a lot of hydrogen

Abstract

The invention discloses a fuel cell testing system capable of performing circular electrolytic hydrogen production. The fuel cell testing system comprises a DC / DC power converter, an electrolytic hydrogen production mechanism, a power distribution mechanism, a hydrogen purification device, a hydrogen cylinder and an upper computer, wherein the power distribution mechanism comprises a power distribution cabinet with a PLC, one input end of the power distribution cabinet is connected with the output end of the DC / DC power converter, and the other input end of the power distribution cabinet is connected with a mains supply. The output end of the power distribution mechanism is connected with the input end of the electrolytic hydrogen production mechanism. A hydrogen inlet of the hydrogen purification device is communicated with a hydrogen outlet of the power distribution mechanism. The hydrogen outlet of the power distribution mechanism is in pipe communication with a fuel cell hydrogen supply system in a fuel cell testing table through a first one-way valve. The output port of the hydrogen cylinder is in pipe communication with the fuel cell hydrogen supply system in the fuel cell testing table through a second one-way valve. The upper computer is respectively connected with the fuel cell testing table, the DC / DC power converter and the PLC. The outlet pressure of the first one-way valve is higher than the outlet pressure of the second one-way valve. The hydrogen electrolyzed by the fuel cell testing system is high in purity and stable in quality.

Description

Technical field [0001] The invention relates to a fuel cell test technology, and more specifically, to a fuel cell test system capable of producing hydrogen by cyclic electrolysis. Background technique [0002] In the traditional fuel cell test process, there are the following shortcomings: 1) The electrical energy generated by the tested fuel cell system is lost through heat consumption, resulting in a waste of resources and an increase in cost. 2) The hydrogen required in the traditional fuel cell test system is supplied by an external hydrogen bottle, and after electrochemical reaction, electricity is generated. In this way, during the entire test process, the supply of hydrogen needs to be manually monitored in real time and supplied in time. When the hydrogen in the hydrogen cylinder is used up, the system will stop running, causing the test to be interrupted. The fuel cell test system runs for a long time and consumes a lot of hydrogen. Summary of the invention [0003] I...
