Development of highly-efficient high-temperature fuel cell systems for stationary applications for a CO2-neutral future

"Two things are required for our line of work: Untiring perseverance and a willingness to throw away something you have put a lot of time and effort into". – Albert Einstein

Dr. Stefanie Wahl

In my group, we work on energy infrastructure focusing electrochemical systems. My tasks include the multiphysical simulation of solid oxide fuel cell systems. We also develop models for determining the lifetime of the systems and to evaluate optimal operation within the specifications to achieve high electrical efficiency.

Interview

Dr. Stefanie Wahl

Dr. Stefanie Wahl

Research engineer for electrochemical systems

Please tell us what fascinates you most about research.

It is exiting for me to explore things and to deal with a topic in depth in order to understand how exactly something works. By thinking out of the box and taking unconventional approaches, we can put the individual puzzle pieces together.

Dr. Stefanie Wahl

What research topics are you currently working on at Bosch?

In our team, we develop complex multiphysical simulation models to ensure power supply in the future. Physical correlations need to be described in such a way to get a predictable simulation model.

What are the biggest scientific challenges in your field of research?

The system is more than the sum of its individual parts. We want to achieve the best possible performance and at the same time a long system lifetime by determining the perfect interaction by various influencing factors. Another challenge is represented by the optimal design of the system with flexible control in order to meet any load requirement in a high dynamic manner. The flexibility of the system in terms of various fuels also represents a key task.

How do the results of your research become part of solutions "Invented for life"?

Through an in-depth understanding of how our systems work, we are designing the future energy sector. The reduction of emissions and primary energy is our contribution toward sustainability. Our highly-efficient systems can be integrated in a decentralized energy landscape in an effort to achieve a CO2-neutral future.
