KELLER Pressure sensors within GreenGT’s fuel cell powertrains is essential for monitoring and controlling hydrogen and air circuits under high- performance conditions. The sensors are employed in several critical subsystems:
Hydrogen loop: The pressure transmitters monitor hydrogen flow within the fuel cell, ensuring optimal pressure levels for efficient electrochemical reactions.
Air loop: Precise pressure measurement is crucial for managing oxygen supply, which directly impacts fuel cell efficiency and power output.
High-pressure hydrogen lines: KELLER Pressure sensors are also used in the high-pressure hydrogen lines of GreenGT’s vehicle prototypes, as well as in the hydrogen-powered test benches and on-board storage systems.
FROM TEST BENCHES TO RACE TRACKS In motorsport, every millisecond counts, and reliability is paramount. The LMPH2G and H24 prototypes operate under demanding conditions, requiring components that can withstand extreme pressures and rapid changes in load. KELLER Pressure sensors play a vital role in maintaining system integrity, ensuring safety, and optimising powertrain efficiency. Beyond competition, the insights gained from racing applications contribute to the development
of hydrogen-powered commercial vehicles. Motorsport serves as a proving ground for future hydrogen mobility, demonstrating its viability under the most demanding circumstances.
SHAPING THE FUTURE OF HYDROGEN TECHNOLOGY
The data and expertise gained from racing fuel cell systems pave the way for broader adoption of hydrogen technology in various sectors, from commercial transportation to energy generation applications.
Whether in the pit lane or on the test bench, precision pressure measurement is a cornerstone of hydrogen innovation.
“To achieve excellence in hydrogen mobility, we need to work with partners like KELLER Pressure who offer products of the highest precision and reliability. The use of «Swiss Made» components in our systems fills us with pride and illustrates our understanding of quality,” comments Frédéric Veloso, business development director, GreenGT.
