Fabrication of Membrane Electrode Assembly for Carbon Nanotubes and Nanofibers-based Catalysts

1 Fabrication of Membrane Electrode Assembly for Carbon Nanotubes and Nanofibers-based Catalysts 

The MEA with CNT-based electrocatalysts are usually prepared by using the conventional process of pasting mixed eatalysts supported on CNTs and Nafion solution onto a gas diflusion layer [63, 71, 81, 187, 188], The method eonsists of, first, preparation of flie eatalyst ink by ultrasonieating appropriate amounts of Pt supported on CNTs, Nafion solution and isopropyl aleohol [188]. The slurry was then eoated on the gas diflusion layer by the brush method and dried at 80 °C. The
