Vedclass · Answer

(B) hydrogen-oxygen fuel cell is an electrochemical cell that converts the chemical energy of hydrogen,which acts as a fuel,and oxygen,which acts as an oxidising agent,into electricity through a pair of redox reactions.In this cell,the cathode reaction involves the reduction of oxygen: $O_2(g) + 2H_2O(l) + 4e^- \rightarrow 4OH^-(aq)$.Since oxygen gains electrons,it acts as the oxidising agent.Thus,option $B$ is correct.

Which of the following acts as an oxidising agent in a hydrogen-oxygen fuel cell?
