Operating Strategies for Solid Oxide Cell (SOC) Reactors in Dynamic Hydrogen Production and Power Load Following

Santiago Salas Ventura, from the Institute of Engineering Thermodynamics, German Aerospace Center, DLR will present at the  14th European Congress of Chemical Engineering and 7th European Congress of Applied Biotechnology (September 17 – September 21, 2023) in Berlin, Germany.

The presentation titled "Operating Strategies for Solid Oxide Cell Reactors in Dynamic Hydrogen Production and Power Load Following," scheduled for September 19, 2023, from 15:35 to 16:00 CET at CityCube Berlin - Room M4, will investigate the critical topic of operating strategies for solid oxide cell (SOC) reactors. These reactors are highly promising energy converters due to their remarkable efficiency in converting the chemical energy of fuels into electrical energy and vice versa.

In solid oxide fuel cell mode (SOFC), they can cover the transient power demand of a ship in combination with batteries. In solid oxide electrolysis mode (SOEC), they can be used to generate hydrogen with renewable sources. Reversible solid oxide cell reactors (rSOC) combine these both modes. While SOFCs present a thermal behaviour according to the load demand, switching between rSOC modes leads to thermal characteristics. In both cases, thermal stresses during the transitions need to be suppressed by operating strategies. To effectively manage this process, scientists have been working on developing strategies that prevent potential damage to the electrochemical reactors.

This effort involves a combination of experimental work and the creation and use of a detailed analytical model to examine these transitions. Key factors such as temperature and voltage characteristics at the cell are carefully considered.
