Catalytic performance of catalyst electrodes.
(a) Cathode cyclic voltammetry (CV) and (b) polarization curves for the 3D nano-architectured electrode with Pt-nanowire arrays (2 mgPt/cm2), the conventional Pt-nanoparticle catalyst electrode (Johnson-Matthey DMFC cathode, 4 mgPt/cm2) and the empty ASP-treated GDL support tested in a 5 cm2 DMFC.
