Abstract

Nanoparticles of Ni and Ni-Al2O3 were coated on a molten carbonate fuel cell (MCFC) anode by spray method to enlarge the electrochemical reaction sites at triple phase boundaries (TPBs). Both nano Ni coated anode and nano Ni-Al2O3 anode exhibited significant reduction of anode polarization, thanks to smaller charge transfer resistance. The maximum power density of nano Ni coated anode was 159 mW cm-2 at current density of 300 mA cm-2 operating at 600 °C. This is about 7% increase from the standard cell performance tested and compared in the study. Although low performance of nano coated Ni-Al2O3 cell is observed due to electrolyte consumption, the stability of cell performance during operation time is more favorable in MCFCs operation.
