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

Q and A
Reducibility is included in mechanism of glucose battery
All of Glucose, Fructose, and Galactose have reducibility, although constructions are different each other.
