Berend van Veldhuizen, from the Delft University of Technology, TUD, will give a speech at the 18th International Symposium on Solid Oxide Fuel Cells (SOFC-XVIII) (May 28 – June 2, 2023) in Boston, USA.
The focus of the presentation, titled 'Experimental Evaluation of SOFC System Exposed to Marine Inclination Conditions,' on May 30, 2023 (17:20-17:40 CET/11:20-11:40 EDT) at Hynes Convention Center - Room 210 (Level Two), will be the evaluation of the influence of marine conditions, in terms of static and dynamic inclinations, on the operation, safety, and lifetime of SOFC systems.
During the experiment that was conducted under the NAUTILUS project, ship motions were simulated with a one-axial oscillation platform. The inclination conditions that the SOFC system was exposed to were derived from ship motion studies and marine regulations.
In the first phase of the test campaign, a 1.5kW SOFC system was inclined around two horizontal axes of rotation while producing power at nominal conditions. The experiment showed no gas leakages or other significant safety risks. However, for slow oscillations, relatively large deviations in several system parameters (e.g., fuel flow, stack voltage, and fuel utilization) were found compared to non-inclined operation.
In the second phase, the test campaign focused on including a wider range of possible ship motions and increasing test durations. An additional aim was to find the physical cause of the deviations in system parameters during oscillations.
The results of the experiments are used to propose design improvements for SOFC systems that require inclination or acceleration. These proposals contribute to the marinization of SOFC systems. The results of this experiment will be used to help class societies define proper regulations for SOFC implementation in seagoing vessels.
