Hyundai Kefico has recently launched a hydrogen leak detector that provides real-time monitoring. To achieve high durability even in harsh environments, Hyundai Kefico relies on Sensirion sensors.

Fuel cell electric vehicles (FCEVs) have become increasingly important in recent years as the demand for cleaner alternatives to petrol and natural gas has grown. FCEVs are similar to other EVs in that they use electricity to power an electric motor. What sets them apart, however, is that FCEVs generate electricity using a fuel cell that is powered by hydrogen, rather than drawing electricity from a battery alone.

In the fuel cell stack, pure hydrogen (H2) flows through a membrane and combines with atmospheric oxygen (O2) to produce electricity. However, because hydrogen has a lower ignition energy than petrol or natural gas and therefore ignites more easily, there is a risk of explosion if the hydrogen leaks.

The answer to this problem is a sensor that constantly monitors the level of hydrogen in the fuel cell. To minimise vehicle failures, Hyundai Kefico has developed a hydrogen gas sensor that detects the smallest hydrogen leaks in vehicles in real time, ensuring driver safety. Once a hydrogen leak is detected, the sensor outputs a signal in the form of analogue voltages. The vehicle can then initiate all relevant safety mechanisms to prevent breakdowns. This makes the sensor ideal for applications such as fuel tanks, delivery systems and fuel cell stacks.

“Sensirion and Hyundai Kefico are both committed to creating a cleaner and more sustainable world. Thanks to this valuable partnership, we have succeeded in developing a hydrogen detector sensor that achieves maximum durability and reliability even in the harshest environments. Together, we are striving to achieve our goal.” Moonsung Shin, Team manager of Sensor Design at Hyundai Kefico.
