In order to investigate the influence of Co layers on the oxygen reduction reaction, a series of Co layers with different nominal thickness have been deposited into the cathode-membrane interface. The polarization curves confirmed visible enhancement in cell performance when a 5 nm Co layer on cathode gave rise to a high current density of 750 mA cm-2 at 0.6 V. Scanning electron microscopy showed that the sputter deposited 5 nm Co layer formed nanosized island structures on the porous electrode, while electrochemical impedance spectra confirmed that a reduction in the total impedance of the electrode led to the improvement of the membrane electrode assembly (MEA) performance. © 2009 Springer Science+Business Media B.V.||Source Title:||Journal of Applied Electrochemistry||URI:||http://scholarbank.nus.edu.sg/handle/10635/86217||ISSN:||0021891X||DOI:||10.1007/s10800-009-9885-3|
