- Bio-ethanol can be used directly as a fuel in molten carbonate fuel cell (MCFC). Unfortunately, the high
water content of bio-ethanol has several negative effects; decrease in performance, electrolyte loss due
to evaporation, and corrosion of anode cell frame. This research was conducted to overcome the negative
effects without degrading MCFC’s performance and stability. A decrease in performance due to low H2
contents was unavoidable. An electrolyte loss was minimized when the recycling method was used. The
optimum recycling ratio was achieved when the flow rate ratio of output to recycle was in the range of
0.7–1. A corrosion of the cell frame was successfully blocked by Ni-electroplated cell frame. This system
was successfully tested for over 2000 h without any decrease in performance.
