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

Options

  1. Aproduce high purity water
  2. Bgenerate heat
  3. Cremove adsorbed oxygen from electrode surfaces
  4. Dcreate potential difference between the two electrodes

Correct answer

D. create potential difference between the two electrodes

Step-by-step 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.
