Construction work for the research factory for hydrogen and fuel cells (HyFaB) began at the ZSW in Ulm in February 2021. The largest independent test site in Europe for fuel cell stacks of up to 250 kilowatts was ready for occupancy after just 15 months. The Baden-Württemberg Ministry of the Environment and Ministry of Economic Affairs are funding the build to the tune of 10.5 million euro. The second construction phase got under way on 23 February 2022 on another building of around 3,000 square metres earmarked for a model factory for the assembly of fuel cell stacks, consisting of production facility, seminar rooms and offices. The systems for the development of stack components and manufacturing processes are scheduled to go into operation in the third quarter of 2023. Prominent figures from politics and industry attended the groundbreaking ceremony where the Minister of Economic Affairs Dr. Nicole Hoffmeister-Kraut presented a grant notification letter confirming funding of 7.75 million euro for this building section (HyFaB-2) from the European COVID-19 Recovery Fund (REACT-EU).
