| Description |
A direct borohydride-hydrogen peroxide fuel cell employing carbon-supported Prussian Blue (PB) as mediated electron-transfer cathode catalyst
is reported. While operating at 30 ◦C, the direct borohydride-hydrogen peroxide fuel cell employing carbon-supported PB cathode catalyst shows
superior performance with the maximum output power density of 68mWcm−2 at an operating voltage of 1.1V compared to direct borohydridehydrogen
peroxide fuel cell employing the conventional gold-based cathode with the maximum output power density of 47mWcm−2 at an
operating voltage of 0.7V. X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Analysis (EDAX)
suggest that anchoring of Cetyl-Trimethyl Ammonium Bromide (CTAB) as a surfactant moiety on carbon-supported PB affects the catalyst
morphology. Polarization studies on direct borohydride-hydrogen peroxide fuel cell with carbon-supported CTAB-anchored PB cathode exhibit
better performance with the maximum output power density of 50mWcm−2 at an operating voltage of 1V than the direct borohydride-hydrogen
peroxide fuel cell with carbon-supported Prussian Blue without CTAB with the maximum output power density of 29mWcm−2 at an operating
voltage of 1V.
