Figure 1
(a) Full cell assembly consisting of two PEEK backplates, two graphite half-cells, a working electrode, the membrane and a counter electrode. (b) Magnification of the half-cell with the interdigitated flow field, electrolyte inlet and outlet ports in green, the reference electrode port in red, and the Cu current collector at the top. (c) CV recorded in 0.1 M KHCO3/K2CO3 Ar-saturated electrolyte with a scan rate of 5 mV s−1. The shaded regions represent the region of eCO2RR/HER (in blue), the non-faradaic region (in gray), the redox reduction (pale orange) and oxidation (lavender), and the OER region (purple).
