PEM electrolysis and SOFC systems

Our journey from prototypes to marketable products

3D graphic of a future hydrogen ecosystem with Bosch PEM electrolyzers and SOFC systems

The present is about foresight. The future is about hydrogen. This is our conviction, and we follow up our words with deeds. We are working on technologies for generating and using green hydrogen. We start at the beginning of the hydrogen value chain: with electrolysis. By the end of the decade, we are planning to invest up to € 500 million in industrializing the Bosch PEM (proton exchange membrane) electrolysis stack, the centerpiece of hydrogen electrolysis. At the same time, we are investing about € 500 million in the development of decentralized power plants based on solid oxide fuel cell (SOFC) technology.

Who are we? We’re an interdisciplinary team with expertise and passion. Under the leadership of Klaus-Frederik Lux and Matthias Ziebell, we are collectively preparing for the market entry of the SOFC system. The electrolysis technology and service activities are led by Carola Ruse and Matthias Ziebell. Our headquarter is at Bosch’s Stuttgart-Feuerbach location; our sphere of influence is the entire world. The energy transition can only succeed if we work together and exchange information with all the players committed to advancing climate protection. The Bosch PEM electrolysis stack and the SOFC system are currently in the pilot phase — we are working flat out to prepare for series production.

Hydrogen is the key to the energy landscape of the future. SOFC systems from Bosch contribute to efficiently utilizing this energy carrier and supporting the transition to a CO₂ emissions-free energy supply. With their flexibility and scalability, they provide tailored solutions for a variety of applications — decentralized, sustainable, and highly efficient.

One important key to the future of a hydrogen economy are technologies that can be scaled to large volumes. That’s how the Bosch PEM electrolysis stack contributes to a demand-oriented and clean hydrogen production with highest efficiency.
