AbstractA novel cathode architecture using vertically aligned Cu nanoneedle arrays (NNAs) as an ordered support for alkaline anion-exchange membrane fuel cell (AAEMFC) application is developed. Cu NNAs are directly grown on a GDL via three steps of electrochemical reaction. After depositing a Pd layer on the surface of Cu by a pulse electrodeposition method to form Pd/CuNNAs, the cathode catalyst layer is formed. The AAEMFC prepared without alkaline ionomer in the cathode catalyst layer shows an enhanced performance with ultra-low Pd loading down to 47 mu g cm(-2), which is much higher than that of a conventional cathode electrode with the Pt loading of 100 mu g cm(-2). This is the first report where three-dimensional Cu NNAs are applied as the cathode support in an AAEMFC, which is able to deliver a higher power density without an alkaline ionomer than conventional MEAs.
