Automated leak testing up to 10-4 mbar l/s


Our patented measuring method makes it possible to determine leakage rates of 10e-4 mbar l/s within 10 seconds. The pressure increase is monitored over the entire test duration. The MAFU evaluation software uses this to calculate the leak rate of the respective bipolar plate. All measurement data is recorded for each product and stored in a database. The combination of speed and accuracy makes the MAFU leak test the ideal solution for quality assurance in your series production.

Leak testing up to 10-5 mbar l/s


Our patented measuring method makes it possible to determine leakage rates of 10e-5 mbar l/s in a short time. The pressure increase is recorded over the entire test duration. The MAFU evaluation software uses this to calculate the leak rate of the respective bipolar plate. All measurement data is recorded for each product and stored in a database. The system is loaded manually and is ideally suited to ensuring quality in the development process

Detection gas: Air, Nitrogen, Helium, Forming gas, Hydrogen
Testing pressure: Atmosphere up to 200 bar

Leak test on fuel cell stacks


Both electrolyser and fuel cell stacks must be highly leak-proof. Various test methods are used to reliably test these complex systems. To ensure a high level of reproducibility, we use precisely controlled test procedures for electrolyser and fuel cell stacks.
