Experiment I Applying the principle to other sugars

Galactose and fructose are kinds of sugar.

We will use glucose, galactose and fructose.

Can we make monosaccharide batteries?

Conclusion

Experiment Ⅰ

・We were able to generate electricity from

fructose and galactose.

・In terms of output voltage

galactose > glucose > fructose

Experiment Ⅱ

・We were able to generate electricity using

common everyday foods. ２２

Future Tasks

・Do more experiments

・Discover if there is any

connection between sugar

concentration and output voltage

Investigate the voltage differences

depending on the type of sugars
