Description

A functionalized activated carbon derived from palm oil empty fruit bunches is utilized as a dispersing agent to synthesize BaCe0.54Zr0.36Y0.1O2.95 (BCZY) powder, which is used as a composite anode. The characteristics of pristine and modified powders are presented and compared. The Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) results confirm the elimination of the intermediate compounds in both powders, thereby promoting single perovskite phase formation. The field emission scanning electron microscopy (FESEM) image demonstrates that the modified powder has a smaller particle size and less agglomeration than the pristine powder. The modified powder's performance in the composite anode of the anode-supported single cell shows lower ohmic and polarization resistances than pristine powder. The improved electrochemical performance of nickel oxide mixed with modified powder indicates the importance of tailoring the pristine powder microstructure as a composite anode for proton ceramic fuel cells.
