 Discuss Question
Answer: Option A. -> Water
Answer: (a).Water
Question 18. How does hydrogen fuel cell work?
  1.    Membrane → hydrogen ions → electric current and recombination with oxygen
  2.    Electric current and recombination with oxygen → hydrogen ions → membrane
  3.    Hydrogen ions → membrane → electric current and recombination with oxygen
  4.    Recombination with oxygen → electric current → membrane → hydrogen ions
 Discuss Question
Answer: Option D. -> Recombination with oxygen → electric current → membrane → hydrogen ions
Answer: (d).Recombination with oxygen → electric current → membrane → hydrogen ions
