Question

what is fuel cell ? give the electrode reaction of hydrogen-oxygen fuel cell.​

Answer 1

Answer:

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.

give the electrode reaction of hydrogen-oxygen fuel cell.

• The oxidation of the fuel (hydrogen) at the anode electrode provides electrons that flow round (via some device e.g. bulb, motor etc.) to the cathode electrode to effect the reduction of the oxygen. So you have simultaneous oxidation and a reduction, therefore overall a redox reaction
