Researchers at the Technical University of Denmark have used Lithoz's ceramic 3D printing technology to create solid oxide fuel cells (SOFCs) with an entirely new structure.

Unlike traditional flat stacking, the new design adopts a bionic spiral-like geometric structure, eliminating the need for interconnects and seals, thereby significantly reducing weight and thermal stress.

Test results show that the new cells achieve a power-to-weight ratio of approximately 1 watt per gram, which is five times that of conventional planar designs (around 0.2 watts per gram). The research team used yttria-stabilized zirconia (8YSZ) material and completed the printing on a Lithoz CeraFab system using a lithography-based ceramic manufacturing (LCM) process.

This monolithic design not only improves volumetric efficiency but also avoids the traditional shortcomings of interconnects and seals in planar stacks. The research team plans to scale this technology for industrial applications, bringing a new design concept to the global hydrogen industry.
