We suggest GA/[GOx/PANI/CNT]n layer as new anode catalyst for EBC.
Proper GOx/PANI/CNT trilayers are organized by opposite charge amid GOx, PANI and CNT.
Superior catalytic activity and EBC performance are obtained by GA/[GOx/PANI/CNT]3.
GA plays a critical role in enhancing EBC stability.
EBC adopting GA/[GOx/PANI/CNT]n layer keeps its MPD even after four weeks.
