Extended Data Fig. 9: Scale-up demonstration using 100-cm2 electrolyser.
From: Coverage-driven selectivity switch from ethylene to acetate in high-rate CO2/CO electrolysis
Photographs of (a) 100-cm2 gas diffusion electrode and (b) integrated electrolysis system used in this work. FE and cell voltage as a function of applied current density over CuO nanosheet catalyst measured in (c, d) 0.1 M KOH under (c) pure CO2 feed and (d) CO/CO2 (3:1) co-feed as well as (e) 1 M KOH under pure CO feed. The KOH flow rate is 120 mL min–1, and the gas flow rate is 750 mL min–1.
