Bipolar plates<\/p>\n<\/h2>\n

\n

Small volumes, minimal leakage rates to be detected and a large number of cavities to be tested are among the challenges in leak testing of bipolar plates. By incorporating sophisticated techniques such as the use of the relative pressure method in conjunction with an external valve block or integrated vacuum testing with tracer gases, we are able to ensure reliable test results.<\/p>\n

We also offer Testing as a Service for bipolar plates.<\/strong><\/p>\n<\/div>\n

Fuel cell stacks<\/h2>\n
\n

Fuel cell stacks have to be highly leak-proof. In order to reliably test these complex systems, various testing methods such as air mass flow are used. To locate leaks with pinpoint accuracy and to ensure a high degree of reproducibility, precisely guided sniffer tests using tracer gases like Helium are applied. Furthermore, we can implement additional steps such as compressing the stacks and marking detected leaks.<\/span><\/p>\n<\/div>\n
