Hydrogen detectors detect hydrogen gas to protect personnel and equipment from potential fire and explosion hazards. They can be found in a variety of applications such as fuel cell technology and industrial settings. With the world shifting away from fossil fuels, the use of hydrogen is poised to play a key role in alternative energy. With this in mind, it’s important to ensure that proper safety procedures are implemented for the production and storage of this highly flammable gas.

Gas Leak Detector (H2) is colorless, odorless, and tasteless, and is very easy to ignite and burn. It is found in a wide range of industrial applications, including cooling systems and fuel cells, as well as in the transportation sector with alternative fuel vehicles and power generators.

The Role of Hydrogen Detectors in Fuel Cell Systems: Ensuring Efficiency and Safety

A H2 detector is composed of electronics and an H2 sensor that converts the detected gas concentration to an electronic signal. This is then used to trigger alarms if the detected concentration exceeds pre-set values.

The sensor in a hydrogen detector is typically an electrochemical type that measures the change of conductivity of a sensor surface due to the presence of the target gas. This is a simple but very reliable and effective measurement.

Other hydrogen gas detection sensors include thermal conductivity and optical types. They can also be integrated into a solid-state device that uses palladium as an electrolyte material. This is a promising development, as it eliminates the need for oxygen for operation and has good selectivity to H2. The IGD pellistor sensor is an example of a solid-state hydrogen detector, which incorporates this advanced technology.
