Hydrogen fuel cells use hydrogen energy as a power source to directly convert chemical energy into electrical energy with high energy conversion efficiency. Compared with the power lithium batteries carried by pure electric vehicles, hydrogen fuel cells are lighter in weight and hydrogenated.3~5Minutes, the cruising range can be as high600kmIt can really realize "lightweight carrying, high density and fast charging".

Due to its advantages of green, pollution-free, low noise, and high power generation efficiency, hydrogen fuel cells are widely used in drones, passenger cars, logistics vehicles, public transportation, heavy trucks, urban special vehicles, storage freight forklifts, and residential power supply. field.

Hydrogen resources are very good, clean, renewable, but it is easy to leak, and the explosion range is very wide, is currently the widest wave range of a gas. Probing for hydrogen is very challenging. Such gases are invisible and tasteless, but volatile and highly flammable, and only need to be contained in the air.4%Hydrogen can produce hydrogen and oxygen gas, sometimes called hydrogen and oxygen mixture (Bang gas), the smallest spark can ignite such gases.

In order to ensure the safety of future hydrogen-fueled vehicles and related infrastructure, it is necessary to detect small amounts of hydrogen in the air, and the response speed of the hydrogen sensor must be fast enough to detect leakage of hydrogen before a fire occurs.

The hydrogen sensor is an indispensable component of the hydrogen fuel cell vehicle safety system. It can monitor the hydrogen concentration in the hydrogen fuel cell vehicle. When the hydrogen concentration exceeds the safety range, the hydrogen sensor will send an alarm signal in time, and the vehicle system will immediately Make corresponding power-off safety protection measures to ensure the safety of passengers in the car.

In addition, the hydrogen sensor can also detect the hydrogen concentration in the exhaust gas of the car, analyze the performance and reaction degree of the reactor in real time, so as to adjust in time to achieve the safe and efficient operation of the car.

However, the hydrogen leak detection device needs a sensor with stable performance and excellent quality to ensure the safety of gas use. It recommend a sensor TGS2616-C00 for detecting hydrogen. This sensor is a semiconductor gas sensor specially developed by Figaro of Japan for detecting hydrogen leak. The TGS2616-C00 contains a newly developed sensitive element, which is little affected by interference gases such as alcohol, and has a high selectivity to hydrogen.
