German hydrogen fuel cell expert Proton Motor Fuel Cell GmbH ( is enabling train and engineering manufacturers, as well as integrators and SMEs, to realize emission-free fuel cell electric drives through its new fuel cell system HyRail.

The company specializes in modular systems using graphitic bipolar plates, as only these meet the technical and commercial requirements of the applications. Due to very high fuel cell performance in conjunction with modularly scalable systems, every performance requirement can be achieved. 

Emission-free "Made in Germany" quality since 1998 

Proton Motor Fuel Cell supplies the HyRail fuel cell system with its own developed and manufactured fuel cells, including control and software with common communication interfaces, such as plug & play, plus the possibility of online monitoring, servicing, and remote access. Optionally, an adapted DC-DC converter can be integrated into the system scope of delivery.

The company, which has been operating successfully internationally since 1998, has established all areas of hydrogen fuel cell development including its series production and testing at a location near Munich in Bavaria, Germany. With more than 100 employees, professional and flexible structures are also guaranteed.

Flagship projects such as the new hydrogen milling train

Proton Motor is optimally positioned for the future as a reliable supplier of alternative green drive technology. Hydrogen as an environmentally friendly energy carrier is also a gain for the railways – and not only in passenger transport. For rail maintenance, exhaust and noise-free cleantech innovations are in demand to amend and substitute overhead cables.

The European specialist has made a name for itself in flagship projects for rail applications. For example, the world‘s first rail milling machine with hydrogen fuel cell drive is based on Proton Motor‘s HyRail fuel cell system. For an Austrian client, the customized fuel cell solution with an installed power of 214 kW was successfully produced and delivered in summer 2021.

Milling concept with renewable energies for CO2 neutrality

Especially in subway tunnels, the high-performance milling machine represents an improvement from an ecological point of view in favor of the desired CO2 neutrality. In addition, the health risk of the operating crew on the track benefits from the zero-emission milling concept, in which the dust pollution – in contrast to previous model series – is eliminated.

For further growth and specific orders, tailor-made HyRail fuel cell systems are to be implemented with innovative train and engineering manufacturers. Proton Motor also prepares the way to emission-free alternative mobility for companies that do not have extensive mechanical resources.
