dc.description.abstract | Exploring efficient approaches to design electrodes for proton exchange membrane fuel cells (PEMFCs) is of great advantage to overcome the current limitations of the standard platinum supported carbon (Pt/C) catalyst. Herein, a Pt/C electrode consisting of double catalyst layers (DCL) with low Pt loading of around 0.130 mg(Pt) cm(-2) is prepared using spray and electrophoresis (EPD) methods. The DCL electrode demonstrated a higher electrochemical surface area (ECSA-52.5 m(2) g(Pt)(-1)) and smaller internal resistance (133 ) as compared to single catalyst layer (SCL) sprayed (37.1 m(2) g(Pt)(-1) and 184 ) or EPD (42.4 m(2) g(Pt)(-1) and 170 ) electrodes. In addition, the corresponding DCL membrane electrode assembly (MEA), which consists of a Pt/C DCL electrode at the anode side and a Pt/C sprayed electrode at the cathode side, also showed improved PEMFC performance as compared to others. Specifically, the DCL MEA generated the highest power density of 4.9 W mg(Pt)(-1), whereas, the SCL MEAs only produced 3.1 and 3.8 W mg(Pt)(-1), respectively. The superior utilization of the Pt catalysts into the DCL MEA can originate from the enrichment of the triple phase boundary (TPB) presented on the Pt/C DCL electrode, which can strongly promote the adsorbed hydrogen intermediates' removal from the anode side, thus improving the overall PEMFC performance. | - |
