What sets us apart
What our quality is based on
As a technology company, we are advancing PEM electrolysis technology by combining our extensive manufacturing expertise with a commitment to rigorous, externally validated quality standards.
Industrialization excellence
Bosch has decades of experience with industrialization and manufacturing of complex technologies.
Automotive DNA
The Hybrion stacks are manufactured to automotive standards for high robustness and durability.
PEM expertise
We leverage years of know-how from innovating PEM fuel cells to directly advance the design, material properties, and performance of our PEM electrolysis stacks.
How we test for performance
We operate systematic testing processes for the validation and optimization of our Hybrion stacks – from single cell to the full-size electrolysis stack.
Comprehensive testing process
This process combines testing at every scale. Through sub-scale-, single-cell and short-stack tests, we achieve a granular understanding of the core processes. In full-size stack testing we verify performance, durability, and real-world readiness.
End-of-line functional testing
Before leaving our plant, Hybrion stacks are tested under real operating conditions to ensure that each stack delivers optimal results for the customer right from the start.
System validation
At our Bamberg site, we operate a hydrogen ecosystem to test our Hybrion stacks under real-world conditions. This unique role as manufacturer, operator, and end-user provides us with deep system-level expertise to continuously optimize our products.
Certifications
Our commitment to engineering excellence and comprehensive testing is validated by leading global authorities. Our certifications: ISO9001, ISO/CSA/ANSI (B)22734, CE, ASME/NRTL, CRN.
