Gyroid 3D‑prints boost fuel cells

DTU researchers 3D‑printed a ceramic solid‑oxide cell with a gyroid (TPMS) architecture that reportedly delivers over 1 watt per gram and withstands thermal cycling while switching between power generation and storage. In electrolysis mode, the design allegedly increases hydrogen production rates by nearly a factor of ten versus standard fuel cells. — If this geometry‑plus‑manufacturing leap translates to scale, it could materially lower the weight and cost of fuel cells and green hydrogen, reshaping decarbonization options in industry, mobility, and grid storage.
