Customized SOFC systems for off-grid power supply

On the basis of SOFC stacks from various manufacturers, there is extensive experience in system integration leading to an operational SOFC system. In the past years, we have implemented fuel cell systems for different fuels, power classes and application areas, such as stationary cogeneration, hybrid systems with coupling of batteries and photovoltaics as well as mobile and maritime systems. The first step in this process is application-based conceptual design together with our customers using long-established design and simulation tools.

Hybrid technologies (coupling with storage systems and generators) and technology-related developments (SOE electrolyzers or reversible high-temperature fuel cells) continue to belong to the work area of the "Energy Concept Systems" and "Systems Integration" groups.
