A novel aluminium-air semi-fuel cell operating with hydrogen peroxide co-generation

► The possibility of generation of H2O2 in original system of Al-air SFC was shown. ► It was study operation of different types of cathodes and ion-exchange membranes. ► Hydrogen peroxide was obtained by a rate 58.3 mg h−1 cm−2 by 85% current efficiency. ► It was shown 15-times (electrode area 100 cm2) scaled up Al-air SFC. ► Al-air SCF can generated H2O2 in diluted water (30 g l−1 NaCl as a catholyte).
