Hydrogen has become an indispensable part of the future energy mix. Our team supported a large research laboratory in the development of new and more efficient fuel cells. In the context of a long-term test carried out over 4 months of a low-temperature polymer electrolyte membrane fuel cell stack, DDM pressure sensors were used in the anode path of the stack. The media compositions at the pressure sensors corresponded to realistic compositions. The involved medium consisted of different concentrations of hydrogen, nitrogen, water vapor and liquid water. The sensing element and pressure connections of our hydrogen-compatible pressure sensors are made from 316L stainless steel. The construction is fully welded and 100% helium leak tested. Each sensor is supplied against a manufacturer declaration for hydrogen use.

More choice of DDM pressure sensors for hydrogen applications
The testing and further development of hydrogen fuel cells is essential in order to meet energy requirements and at the same time achieve climate targets. In addition to our PV22 H2, the PV25, PX25 and PV15 products now also have an approved manufacturer’s declaration for use in hydrogen applications.
The key facts on application suitability at a glance:
- Medium: Hydrogen up to 100% concentration
- Operating pressures: 0 to 5 bar absolute (0 to 4 bar relative/ subject to higher measuring ranges)
- Media temperature: -20 to +80°C
The typical test bench sensors of the PX25 series have been tried and tested for a long time and have the option of a 4-20mA output signal. The PV15 is our smallest sensor and can also be used in applications with very small installation spaces.
In August, we again supplied our PV25 pressure sensors to a renowned research institute in Germany for testing fuel cells. We are proud to support important research at an early stage of development with our technology.
