DTU explores printed ceramic gyroids for lighter fuel cells

What happened

Researchers at the Technical University of Denmark used a Lithoz CeraFab system to produce thin-walled zirconia gyroid structures for solid-oxide fuel cells. The design replaces the conventional flat-layer arrangement with a continuous three-dimensional geometry.

Lithoz reports a fivefold improvement in device-level power-to-weight performance compared with the flat cells used in the comparison. This is a research result for the tested architecture, not a universal fuel-cell efficiency gain.

The team plans to scale the approach toward industrial use. Manufacturing repeatability and system integration remain separate steps from demonstrating a promising printed cell.
