Long-term DMAFC voltage of PVA/40.5% ZIF-8 membrane at 60 °C at current density of 50 mA cm⁻² using catalyst of 2 mg cm⁻² Pt–Ru on carbon cloths and 1 mg cm⁻² Pt on carbon cloths with micro-porous layer (MPL) for anode and cathode respectively (2 M methanol with 6 M KOH at a flow rate of 5 mL min⁻¹ for anode fuel and humidified oxygen at a flow rate of 100 mL min⁻¹ for cathode feed). The anode fuel was replenished after 93 h.
