Green Energy: An Integrated Solution for Fuel Cells

The humidity sensor for Hydrogen applications is still a new topic for sensor manufacturers because the applications in this special field are not thoroughly tested.

Allengra is involved with this technology since 2020, and developed a solution which passed the prototyping stage with very promising results.

Key Features of the Hydrogen multifunctional sensor:

• Measuring Flow (volume and Mass) - up to 1000l/min
• Temperature metering – 0 – 80 °C
• Humidity – 0 – 100 RH
• Pressure – 1 – 16 barA
• Mixing ratio of two gases (e.g. H2 - N2) – 3 – 5%

Applications:

• PEM Fuel Cells, crucial features for anodic recirculation path
• Hydrogen ICE
• Electrolysers
