This article introduces a novel electrode assembly that integrates 3D-printed microlattice carbon electrodes with bipolar membranes (BPMs) for bicarbonate electrolysis. The design, enhanced with silver nanoparticle coatings, significantly improves CO production efficiency and stability compared to uncoated electrodes. With minimal performance loss over extended operation and promising techno-economic prospects, this approach highlights the potential of combining additive manufacturing and BPM technology to advance sustainable electrochemical CO₂ reduction toward commercial viability.
