Short Summary
This study introduces the first stereolithographic 3D-printed microlattice carbon electrodes integrated with bipolar membranes for bicarbonate (CO2) electrolysis. Using projection micro-stereolithography (PμSL), precisely engineered honeycomb-structured electrodes were fabricated to enhance mass transport and improve CO2 generation and utilization at the membrane–electrode interface. The work bridges additive manufacturing and electrochemical reactor design, establishing a new pathway toward advanced membrane–electrode assemblies for efficient CO₂ conversion.
