Question

Q.5 How does a fuel cell operate ? Draw a well labelled
digram to illustrate it and also show the
Chemistry of working of a H₂O2 fuel cell?
​

Answer 1

In order for a fuel cell to work, it needs hydrogen (H2) and oxygen (O2). The hydrogen enters the fuel cell at the anode. A chemical reaction strips the hydrogen molecules of their electrons and the atoms become ionized to form H+. The electrons travel through wires to provide a current to do work.
