Description

technical field [0001] The invention relates to a high-safety fuel cell test platform and its integrated hydrogen supply system, which is especially suitable for testing small-scale fuel cells (1-1000 W) in university laboratories and other research units that have high safety requirements. Performance Testing. Background technique [0002] A fuel cell is a device that directly generates electrical energy from chemical energy through an electrocatalytic reaction. It has many advantages such as high energy conversion efficiency, high power density, low noise, and high environmental protection. Among them, the proton exchange membrane fuel cell (Proton Exchange Membrane Fuel Cell, PEMFC), which uses hydrogen as the fuel gas and can operate at low temperature (<100 ℃), due to its high technology maturity, the product is pure water and has high energy / Power density has become an ideal solution for future new energy vehicles, distributed energy systems and grid architectures...

AI Technical Summary

Problems solved by technology

[0006] 1. The hydrogen source required by the test platform uses an external steel cylinder, and requires a relatively complicated pipeline system to connect to the test platform, which has potential safety hazards, and many research institutes and structures have mandatory regulations for fire safety considerations. Hydrogen cylinders are not allowed in the room, causing additional difficulties for the configuration of the test platform

[0007] 2. Existing commercial fuel cell test platforms generally do not consider the treatment of exhaust gas. Basically, the excess fuel gas is discharged directly or simply through water treatment. Once the test site is not well ventilated, gas accumulation is likely to occur. security risks

[0008] 3. Hydrogen will be in contact with the external environment when passing through the gas humidification system, and it is impossible to achieve a completely closed hydrogen internal circulation
