Hybrion PEM Electrolysis Stacks
With the Hybrion PEM electrolysis stacks (PEM = proton exchange membrane), Bosch delivers the heart of your PEM electrolyzer. Our many years of experience in industrialization and automation are incorporated into the production of the stacks, of course, with the excellent Bosch quality you expect.
Technical data
Efficient, powerful, reliable – our Hybrion stack produces 22,9 kilograms of hydrogen per hour at an output pressure up to 34 bar. This is equivalent to a power input of up to 1.25 megawatts.
Benefits at a glance
Bosch Quality
Many years of experience with series production, automation and AIoT solutions flow into our electrolysis technology
Cost Efficiency
Enabling low Levelized Cost of Hydrogen (LCOH) due to high volume production and efficient stack design
Reliability
thanks to robust technology and production based on automotive standards
Scalability
Maximum flexibility and possibility of industrially scalable high-volume production through the stack's modular character
Compatibility
with renewable energies such as wind and solar power
Low integration effort
through compatibility with existing container and large-scale industrial solutions
Made to Scale.
Using our core competence of scaling and industrialization, we provide hydrogen production solutions – for use in decentralized systems for covering the energy requirements of the user's own production facilities, hydrogen filling stations up to large-scale industrial production.
Double the hydrogen. Same footprint.
We are continuously advancing hydrogen technology. That's why we are working on the next performance level for our Hybrion PEM electrolysis stack: double the hydrogen production within the same footprint. Designed for the 2.5 MW class, it supports hydrogen production on an industrial scale. For you, this means more hydrogen per square meter of plant space.
Our strong partnerships are key to the stack's success. We provide a full suite of services for our Hybrion PEM electrolysis stacks, including long-term performance assurance, technical support, and seamless commissioning. Customers also benefit from expedited premium delivery and professional end-of-life disposal services.
The commissioning of Bosch Hybrion PEM electrolysis stacks for customers started in 2025. All technical specifications given are development objectives and refer to the beginning of life.
