The development of low-Platinum content polymer electrolyte fuel cells (PEFCs) has been hindered by inexplicable reduction of oxygen reduction reaction (ORR) activity and unexpected O2mass transport resistance when catalysts have been interfaced with ionomer in a cathode catalyst layer. In this study,...
A membrane electrode with ultra-low oxygen mass transfer resistance includes an anode catalyst layer, a proton exchange membrane (PEM), and a cathode catalyst layer. A catalyst in the cathode catalyst layer is negatively charged, and the cathode catalyst layer is further doped with a negatively ...
1h). Meanwhile, the decreased energy barrier for K+ ion desolvation is further demonstrated by the electrochemical impedance spectroscopy (EIS), in which 0.4 M KPF6-DME exhibits a relatively low charge-transfer resistance (Rct) (Supplementary Fig. 6 and Supplementary Table 3). Overall, this...
