Reliable operation of Proton Motor fuel cells: An Application Report by Buerkert Fluid Control Systems

Functionally integrated system solutions for hydrogen supply and water separation

Buerkert’s fluidics components have consistently demonstrated their reliability in many hydrogen applications to date. Turnkey system solutions for anode supply and water separation were developed for the fuel cells produced by Proton Motor Fuel Cell GmbH. One constructive way to address the climate crisis and reduce carbon footprint is the use of green hydrogen. Fuel cell systems are both an environmentally-friendly and sustainable energy-supply solution in stationary and mobile applications alike.

Fluidics components play an important part in ensuring that they can function reliably and safely. Buerkert’s functionally integrated system solutions, featuring advanced valves and sensors, guarantee precise hydrogen dosing, secure hydrogen shut-off, and accurate water separation within the anode circuit of the fuel cells. These compact solutions are designed for seamless integration with fuel cell stacks.

Precise and safe hydrogen dosing

With the HyStack® 400, Proton Motor Fuel Cell GmbH has developed compact fuel cell modules that deliver power ranging from 21.3 to 49.7 kW, making them suitable for a wide range of applications. In the HyShelter® (product picture), the scalable fuel cell modules are arranged into a hybrid, turnkey container solution.

Robert Baustaedter, Fuel Cell Engineering at Proton Motor: “We were looking for a tried-and-tested, turnkey system solution for our module hydrogen supply and water separation that would meet our fluidic requirements and provide a tailored interface to the fuel cell stack module. Such systems are critical for the operation of the fuel cell, as they regulate the supply of hydrogen at the anode inlet as well as being responsible for safety shut-off. At the anode outlet, they must also ensure proper gas purging as well as water separation.”
