Molten carbonated fuel cells are notable as power generation systems because of its
high efficiency and relatively clean conversion of chemical energy into electrical energy.
In this work, the anode electrode for molten carbonate fuel cell was synthesized. The
positive effect of nickel boride as an additive in nickel anode electrode was investigated.
Nickel boride was synthesized by chemical reduction with solvo-thermal route. Reduction
reaction of nickel chloride hexahydrate salt with sodium borohydride was performed
for nickel boride synthesis. Result of reaction, both nickel boride and hydrogen were
produced and then nickel boride was put into reactor kept at 350°C for 12 hours to
provide solvo-thermal conditions. Obtained nickel boride was added to green sheet.
Green sheets were subjected to sintering operation to get anode electrodes. As a result
of SEM analysis, average particle size for without and with additive anode electrodes
were calculated as 4,4 μm and 3,4 μm respectively. According to EDAX results, atomic
percent of nickel for without/with additive anode electrods were found %44,34 and
%83,13 respectively.
