In Measurement was done under galvanostatic mode, with constant applied current of 100 mA (20 mA cm -2 ). The above-mentioned electrodes were used as anodes and cathodes, and the anion-exchange membrane is Fumasep FAA-3-50 (fumatech). Experiments were performed for 1 hour with 1 M glycerol/1 M NaOH as anolyte and 1 M NaOH as catholyte, circulated through the MEA bipolar plate flow channels from the respective electrolyte reservoirs using a dual-channel peristaltic pump (JIHPUMP BT-EA-50) at 50 rpm flow rate. N2 (Zero Grade, BOC) was used as purging gas to the electrolyte reservoirs to maintain an inert atmosphere.
