Advancing the Frontiers of Solid Oxide Cell Technology

At Dynelectro, we actively contribute to the global research community driving the transition toward sustainable, high-temperature electrolysis. Our recent collaborations and scientific presentations highlight new insights into durability, scalability, and feedstock flexibility in solid oxide electrolysis (SOEC) and co-electrolysis systems.

Thomas Erik Lyck Smitshuysen – The Necessity of AC:DC for Long-Term Operation

20,000 hours of operation on a 70-cell SOEC stack

Thomas Erik Lyck Smitshuysen’s work demonstrates a major leap in SOEC longevity through alternating AC/DC operation. By switching between electrolysis and fuel-cell modes several times per second, the system achieves a stable thermal balance and drastically reduces degradation. This breakthrough marks one of the longest continuous SOEC operations to date—20,000 hours—and underscores Dynelectro’s unique AC:DC approach to sustainable hydrogen production.
