The aluminium fuel
cell consists of an aluminium anode and an air cathode. As in previous
experiments, the power from the cell was calculated by varying the voltage. The
fuel in this case was once again methanol. The whole arrangement is similar to
previous experiments.
RESULTS
As
it can bee seen form the graph above, the power from the cell was increasing
linearly with the voltage. The maximum value was 100 mW at 0,5 mV.
The
aluminium/air cell , compared to the hydrogen and methanol fuel cells , can
produce fairly considerable amounts of energy. This is due to the energy density
of the aluminium anode. Therefore the size of such a cell can be smaller
compared to others. Nevertheless the anode is sacrificed in the oxidisation
reaction and will require replacement. This may be expensive as the anode is
battery grade aluminium and the cell may have to be completely dismantled to
allow the new anodes to be fitted.
