• A systematic study for the effect of porous structures on CO production was performed.

• Different performance trends between H-cell and full cell analyses were observed.

• A thin catalyst layer possessing mesopores promoted CO production in MEA condition.

• The optimized catalyst exhibited the highest energy efficiency (55 %) at 265 mA cm−1.
