Liu et al. synthesized fully aromatic poly(ether ketone)s based on the monomer p-biphenyl-hydroquinone. Then they prepared site-selective sulfonated biphenyl-ated poly(ether ether ketone)s (BiPh-SPEEKDKs) by mild and rapid sulfonation reactions. MEA fabrication and fuel cell operating conditions were conducted according to Los Alamos National Laboratory protocols. The cell was preconditioned under H2/air fuel cell operation at 0.7 V for 2 h. Pt-Ru black was used for anode and Pt black for cathode and 5% commercially available Nafion dispersion. The catalyst ink was painted onto the membrane until the catalyst loading reached 8 mg cm for anode and 6 mg cm for cathode. Active area is 5 cm. The cell was held at 80°C 1 and 2 M aqueous methanol solution was fed to the anode with a flow rate of 1.8 mL min- 90°C humidified air was fed at 500 seem without back pressure. The current density of BiPh-SPEEKDK at 0.5 V at 80°C in 1 and 2 M methanol reached...
