Fuel cell electric vehicles (FCEV) powered by hydrogen are climate-friendly in addition to powerful. Glorious growing demand for these zero-emission drives is currently focused first of all 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 in their fuel tanks.
Compared to the now widespread electric motors with batteries, the much more expensive hydrogen fuel cells facilitate a much greater range, with an identical power rating to a petrol or a diesel engine. Also, H2 vehicles could be refuelled in minimal time at all, in comparison with the charging times necessary for batteries.
The capability of a hydrogen tank is governed by its physical size but also by its storage pressure: The bigger 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 also have been created for use in vehicles. Marked Down affects the mechanical construction in respect of shock and vibration resistance, together with electromagnetic compatibility (EMC).
To ramp up the sales of hydrogen-fuelled commercial vehicles and cars, the correct network of filling stations should be expanded. With Greatness -3, for instance, the WIKA portfolio also contains a suitable sensor for filling stations, made with explosion protection.
