Electrochemical cells AQA A Level chemistry

Which fuel cell equations do we need to memorise please?
e.g ethanol and oxygen

i thought it was just the equations for hydrogen fuel cell and the rechargeable battery with lithium and cobalt? if u look at the spec it says:

The simplified electrode reactions in a lithium cell:

Positive electrode: Li+ + CoO2 + e– → Li+[CoO2]–

Negative electrode: Li → Li+ + e–

Cells can be non-rechargeable (irreversible), rechargeable or fuel cells.

Fuel cells are used to generate an electric current and do not need to be electrically recharged.
