However, no attempts have been made for the integration of all developed components into a PEMFC system. In this study, we successfully integrated a highly active Pt3Ni/C catalyst, a multiscale/multilevel membrane with a plasma etching process, and a flow-field bipolar plate with a micro-channel into a single-cell assembly, and achieved excellent PEMFC performance. Specifically, we obtained a maximum power density of more than 1.6 W/cm(2) with low catalyst loading of 0.125 mgPt/cm(2) (0.125 mgPtNi/cm(2)) at the anode (cathode) from the synergetic effects of the improved kinetics of oxygen reduction reaction, reduced ohmic resistance, and enhanced mass transport with the integration of each developed component. Furthermore, a current density of 2.61A/cm(2) at 0.6 V was achieved with catalyst loading of 0.2 mgPt/cm(2) (0.4 mgPtNi/cm(2)) at the anode (cathode).
