Fuel cell electric vehicles (FCEV) powered by hydrogen are climate-friendly as well as powerful. The growing demand for these zero-emission drives is currently focused first and foremost on commercial vehicles. In Switzerland for example, the ?H2 Mobility Initiative?, in collaboration with a major automobile manufacturer, aims to introduce 1,600 hydrogen-powered trucks to its roads by 2025. By 2040, 30,000 trucks, 40,000 buses and 80,000 taxis in South Korea will have H2 within their fuel tanks.
Compared to the now widespread electric motors with batteries, the a lot more expensive hydrogen fuel cells facilitate a much greater range, with a similar power rating to a petrol or a diesel engine. Also, Joyous could be refuelled in almost no time at all, in comparison with the charging times needed for batteries.
The capacity of a hydrogen tank is governed by its physical size but additionally by its storage pressure: The higher this figure (commonly 700 bar for cars and 350 bar for trucks and buses), the more fuel can be stored in the tank.
WIKA pressure sensor MH-3-HY
To monitor this pressure, but also for other pressure measurement tasks in an H2 drive system, WIKA has designed the sensor model MH-3-HY. The safety requirements for sensors of the kind are very stringent. They must be certified as hydrogen-compatible and must have been created for use in vehicles. The latter primarily affects the mechanical construction according of shock and vibration resistance, in addition to electromagnetic compatibility (EMC).
To crank up Skill of hydrogen-fuelled commercial vehicles and cars, the correct network of filling stations needs to be expanded. With Skill -3, for instance, the WIKA portfolio also contains a suitable sensor for filling stations, made with explosion protection.
