TECHNOLOGY DESCRIPTIONS

HIGH ACCURACY PRESSURE DECAY LEAK TESTING

Differential pressure decay works by pressurizing a part and measuring for a drop in pressure. Even if a part is sealed with no opening to pressurize, there are ways to use chambers for ingress testing…..more details, application, example, specs and description…

TESTING INSTRUMENTS

The air side is typically tested for leaks with an air pressure decay. The fuel cell’s semi-permeable membrane should be tested for air flow and the vehicle’s cooling system is leak tested with an air tester.

H6000 ATEQ E-MOBILITY

The fuel side components are typically tested for leaks with a mix of 5% H2 (hydrogen) and 95% N2 (nitrogen) called forming gas. Contrary to pure hydrogen, forming gas is not flammable, and it helps detect defect areas that hydrogen could flow through. H6000 is the solution.
