英文摘要	vulcan xc-72r, ketjen black ec 300j and black pearls 2000 carbon blacks were used as the additive in pt black cathode catalyst layer to investigate the effect on direct methanol fuel cell (dmfc) performance. the carbon blacks, pt black catalyst and catalyst inks were characterized by n(2) adsorption and scanning transmission electron microscopy (stem) with energy dispersive x-ray (edx) spectroscopy. the cathode catalyst layers without and with carbon black additive were characterized by scanning electron microscopy, edx, cyclic voltammetry and current-voltage curve measurements. compared with vulcan xc-72r and black pearls 2000, ketjen black ec 300j was more beneficial to increase the electrochemical surface area and dmfc performance of the cathode catalyst layer. the cathode catalyst layer with ketjen black ec 300j additive was kept intimately binding with the nafion membrane after 360 h stability test of air-breathing dmfc.
