As can be seen from the device diagram, the reaction on the left electrode is that organic matter is oxidized and escapes into CO 2, and the electrode reaction formula is C6h12O 6+6H 2 O-24e-6CO2 ↑+24h+,which is an oxidation reaction, while the reaction on the right electrode is that O 2 gains electrons and becomes H2O, and the electrode reaction formula is O 2 +4e-+4H+=2H 2 O, which is a reduction reaction. Therefore, m is the negative electrode and n is the positive electrode. According to the principle that like charges repel and opposite charges attract, when the battery works, H+ moves from the M-pole region to the N-pole region. If the N electrode consumes 5.6 L (standard temperature and pressure) O 2, then the electron transfer N (e-) = "(5.6" L ÷ 22.4 L/mol) × 4 = "1mol", then N A H+ passes through the ion exchange membrane. Therefore, the wrong option is d.
