N2 - Direct formic acid fuel cells (DFAFCs) MEAs were fabricated by using Pt black and Pt/C as cathode catalysts, with various amount of Nafion ionomer. The effect of ionomer content on oxygen reduction reaction (ORR) activities was examined by single cell test, and the MEAs were electrochemically characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Especially the ionic resistances of cathode layers were measured by the complex capacitance analysis of experimental impedance data. The influence of charge transfer reaction on Pt and mass transport of proton and oxygen in the catalyst layers (CL) were discussed for the DFAFC MEAs based on Pt black and Pt/C catalysts.
