Practise IB Chemistry HL 3.2.6 by applying primary (voltaic) cells to exam-style questions.
As well as being burnt, methanol can also be used to provide electricity through a fuel cell. A schematic diagram of such a fuel cell, that depends on the transfer of hydrogen ions between the electrodes, is shown below.

Even though fuel cells, primary cells and rechargeable cells have similar fundamental characteristics, there are important differences between them.
Suggest a way in which they are similar.
