Hydrogen is an energy carrier that is easy to store, transport, and use. Hydrogen, as a clean energy source, only produces water, electricity, and heat through chemical reactions in fuel cells. Hydrogen energy has been widely used in fuel cell electric vehicles (FCEVs) and hydrogen storage systems. As a highly sensitive non-destructive leak testing technology, it meets the leak testing requirements of fuel cell hydrogen storage systems.
The helium mass spectrometry leak detection method can achieve:
Quickly and reliably test the leakage of bipolar plates and fuel cell stacks.
Conduct overall and quantitative high-sensitivity leakage testing on hydrogen circuit components such as anode circulation pumps and hydrogen injectors.
Bipolar plate: Vacuum technology is used for plasma activation and sputtering coating on the surface, which can significantly improve the corrosion resistance of metal bipolar plates and reduce contact resistance In terms of leak detection limit and speed, Shanghai Bodong recommends using helium mass spectrometry leak detection, micro flow air leak detection, or a combination of both.
Fuel cell stack (hydrogen storage tank): After the assembly of fuel cell stack, leak detection is crucial for the subsequent production process The integrity of the battery stack, including mechanical damage to individual batteries and uniform force distribution of clamping devices, can be checked through either the overall microfluidic testing method or the local helium mass spectrometry leak detection method.
Hydrogen circuit components: In travel applications, hydrogen leakage must be minimized Many components in the hydrogen circuit, such as injection valves or circulation pumps, need to undergo leakage testing This also applies to many other components in the air/oxygen circuit, as well as the cooling of fuel cells and power electronics equipment.
