Hyundai Kefico, a South Korean manufacturer of vehicle components and systems, has introduced a new hydrogen gas sensor capable of detecting even the smallest leaks in onboard vehicle systems. The sensor hardware was supplied by Sensirion, a German sensor specialist.

The sensor operates in real time to rapidly detect any anomalies and ensure driver safety. Once a hydrogen leak is noted, the sensor outputs a signal in the form of analogue voltages. The vehicle systems can then initiate the relevant safety mechanisms.

“Sensirion and Hyundai Kefico are both committed to creating a cleaner and more sustainable world,” said Moonsung Shin, team manager for Sensor Design at Hyundai Kefico.

“Thanks to this invaluable partnership, we have succeeded in developing a hydrogen detector sensor that achieves maximum durability and reliability, even in the harshest environments.”

The new sensor is particularly important considering the anticipated proliferation of hydrogen-fuelled vehicles using both H2 internal combustion and fuel cells. Hydrogen has a lower ignition energy than petrol or natural gas (methane), allowing it to combust more easily. Sensing leaks is critical to vehicle security.

The new sensor can be used across the H2 fuel system, including fuel tanks, delivery systems and fuel cell stacks.
