​

Answer 1

Answer:

A fuel cell uses the chemical energy of hydrogen or another fuel to cleanly and efficiently produce electricity. ... Fuel cells are unique in terms of the variety of their potential applications; they can provide power for systems as large as a utility power station and as small as a laptop computer.

Answer 2

Answer:

The hydrogen or any other fuel is oxidised electrochemically inside the fuel cell to produce a potential difference i.e. a voltage capable of producing a working current. The overall chemical reaction in a hydrogen fuel electrochemical cell involves the oxidation of hydrogen by oxygen to produce only water.
