Overview

• DTU Energy and DTU Construct published the monolithic gyroid solid oxide cell in Nature Energy on July 18, with a News & Views describing it as a promising breakthrough.
• The fully ceramic build removes metal parts that typically make up over 75% of system weight and is produced in just five steps without fragile seals.
• Tests report specific power exceeding 1 watt per gram, meeting the watts-to-gram ratio researchers cite for aerospace use.
• In electrolysis mode, the device generated hydrogen at nearly ten times the rate of conventional designs.
• The cell withstood 100°C thermal swings and repeated mode switching without structural failure; the concept is backed by a 2024 patent and Villum P2X funding, with further material optimizations proposed.
