This research utilizes CO2 gas to become methanol through an electrochemical method using a Membrane electrode assembly (MEA). The MEA used consists of MEA-A with a Microporous layer (MPL) layer on the cathode and MEA-B which does not have an MPL layer. The electrode on the MEA has a different catalyst composition, where the cathode uses a Cu2O-ZnO/C catalyst while the anode uses Pt/C. The cath…
