An inventor proposes using a SHE (standard hydrogen electrode) in a new battery for smartphones that also removes toxic carbon monoxide from the air:Anode: CO(g) + H2 O(l) ⟶CO2(g) + 2H+(aq) + 2e−      E°anode = −0.53 VCathode: 2H+(aq) + 2e− ⟶H2(g)                                 E°cathode = 0 V                                                                                                                                    Overall: CO(g) + H2O(l)⟶CO2(g) + H2(g)                     E°cell = +0.53 VWould this make a good battery for smartphones? Why or why not?

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
