Vedclass · Answer

(B) In a hydrogen-oxygen fuel cell,the following reactions take place to create a potential difference between the two electrodes:Anode: $2H_{2(g)} + 4OH^{-}_{(aq)} 	o 4H_2O_{(l)} + 4e^{-}$Cathode: $O_{2(g)} + 2H_2O_{(l)} + 4e^{-} 	o 4OH^{-}_{(aq)}$Overall reaction: $2H_{2(g)} + O_{2(g)} 	o 2H_2O_{(l)}$The net reaction is equivalent to the combustion of hydrogen to form water,which facilitates the flow of electrons and creates a potential difference.
