A) \[2{{H}_{2}}+{{O}_{2}}\xrightarrow{{}}2{{H}_{2}}O(l)\]
B) \[{{H}^{+}}+O{{H}^{-}}\xrightarrow{{}}{{H}_{2}}O\]
C) \[{{O}_{2}}+2{{H}_{2}}O+4{{e}^{-}}\xrightarrow{{}}4O{{H}^{-}}\]
D) \[{{H}^{+}}+{{e}^{-}}\xrightarrow{{}}\frac{1}{2}{{H}_{2}}\]
Correct Answer: C
Solution :
In hydrogen-oxygen fuel cell, the following reaction occurs at cathode, \[{{O}_{2}}+2{{H}_{2}}O+4{{e}^{-}}\xrightarrow{{}}4O{{H}^{-}}\]
