Fluidic solutions for mobile fuel cell technology

The mobile fuel cell efficiently supplies electrical energy by converting hydrogen to provide an environmentally friendly power source for mobile applications such as vehicles for travelling. In mobile fuel cells, armature, i.e. the management of gas and liquid flows, is an important aspect in ensuring efficient and reliable power generation for the actuator. 


As an armature specialist, Bürkert is the ideal partner at your side. See for yourself!

Hydrogen meets fluid experience logo

What is important in fluidic control and how does it help with issues such as reliability and increasing the efficiency of mobile fuel cells?

It is crucial for both the electrical and mechanical components used in the fuel cell to work safely and reliably in order for it to be used in mobile applications. In order to avoid downtime and minimise maintenance costs, it must be guaranteed that they can function under harsh operating conditions for a long period.


Bürkert products and solutions meet very high safety requirements thanks to the necessary approvals and durability. Long maintenance intervals and energy-saving solutions contribute to the efficient utilisation of your fuel cell. Our components are suitable for use with hydrogen and guarantee reliable operation.

Flushing and draining the recirculation circuit

Efficiently controlling hydrogen in mobile fuel cells not only enables an efficient fuel supply, but also plays a decisive role in flushing and draining the recirculation circuit. This precise control not only helps to increase the performance and extend the service life of the fuel cell by protecting against undesirable chemical reactions and wear, but also ensures long-term operational reliability and protects against unexpected failures.
