ATEQ Leak Testing Technology for EV Fuel Cells

Fuel Cells are becoming popular in the e-mobility industry because fuel cell systems are a clean, efficient, reliable, and quiet source of power. A fuel cell creates electrochemical reactions between hydrogen and oxygen to generate electricity, heat and water. A fuel cell is composed of an anode, cathode, and an electrolyte membrane.

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. The air side is typically tested for leaks with an air pressure decay or mass flow instrument. 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.
