Fig. 2: CO2RR performance and selectivity of the Cu-based catalysts in each cell configuration.

From: Exploring the influence of cell configurations on Cu catalyst reconstruction during CO2 electroreduction

Fig. 2

Cell configurations of the (a) H-type cell and (d) MEA cell. C2+ current densities of the Cu2O cube, Cu2O aggregate, and cCu in the (b) H-type cell and (e) MEA cell. C2+/C1 ratio of the Cu2O cube, Cu2O aggregate and cCu in the (c) H-type cell and (f) MEA cell. All error bars represent the standard deviation calculated from at least 3 data points. The applied potentials of the H-type cell were converted to RHE with 85% iR compensation, while the cell voltages for the MEA cell were presented as non-iR corrected values.
