The gas-phase CO2 electroreduction to formate represents one of the most promising conversion processes due its scalability, as product concentration surpasses 30 % wt. However, use alkaline media anolytes, intended improve efficiency and selectivity production, causes carbonate bicarbonate salts precipitate over Gas Diffusion Electrode (GDE). This precipitation clogs porous structure, leading a rapid loss electrode stability. In this work, we address issue by proposing acid based on K2SO4, mitigate insoluble salt GDE thereby achieving longer more stable operation times. Various anolyte concentrations pHs are evaluated, with 0.3 M K2SO4 at pH 1, adjusted using H2SO4, providing best compromise. condition inhibited potassium precipitation, observed through XRD, SEM, EDS analysis, while maintaining high performance, 69 g L−1, Faradaic Efficiency 33 %. Furthermore, flowrate per geometric area is optimized maximize system performance. At 0.85 mL min−1 cm−2, enhanced 88 L−1 42 reached. Besides, long-term experiments demonstrated that GDEs used conditions exhibit larger deactivation constant (0.7652) compared anolytes (0.3891). indicates rapidly reduces performance under conditions. These results represent advance in obtaining longer-lasting GDEs, which crucial successfully scaling up formate.
