In a hydrogen–oxygen fuel cell, combustion of hydrogen occurs to

A
produce high purity water
B
generate heat
C
remove adsorbed oxygen from electrode surfaces
Correct answer
D
create potential difference between the two electrodes

Solution

Any cell [like fuel cell], works when potential difference is developed.In a hydrogen–oxygen fuel cell, combustion of hydrogen occurs tocreate potential difference between the two electrodes.

Hence, the correct answer is option: 'D'.
