ʻAkika Formic Nā Kelepona Wahie
Hoʻohana ʻia ka waikawa formic ma ke ʻano he wahie i loko o nā cell wahie waikawa formic pololei (DFAFCs). I loko o kēia mau cell wahie, hana ka waikawa formic ma ke ʻano he wahie, e hana ana i kahi hopena oxidation ma ka anode e hoʻokuʻu i nā electrons a hoʻoulu i ka ikehu uila. Hāʻawi nā DFAFC i nā pono e like me ke kiʻekiʻe o ka ikehu a me nā mahana hana haʻahaʻa, e paʻa ana i nā noi hiki ke hoʻohiki ʻia i nā mea uila liʻiliʻi a me nā kumu mana lawe lima.

Nā Pōmaikaʻi o nā Pūnaehana Wahie Formic Acid (DFAFCs)
ʻO nā cell wahie waikawa formic pololei (DFAFC) ke kū nei ma ke ʻano he ʻenehana hoʻololi ikehu electrochemical hoʻohiki nui, e hāʻawi ana i kahi hui kūikawā o ka palekana kiʻekiʻe, ka pono kūikawā, a me ka hana pono e hoʻoponopono ai i nā palena koʻikoʻi o nā koho ʻē aʻe i hoʻokumu ʻia i ka hydrogen a me ka methanol.
Ma ke ʻano he wahie wai i ka mahana o ka lumi a me ke kaomi lewa, hoʻopau ka waikawa formic (HCOOH) i ka pono no ka hoʻopili ʻana i ke kaomi kiʻekiʻe a i ʻole ka mālama cryogenic, e hōʻemi nui ana i nā kumukūʻai o ke kahua a me nā pilikia palekana e pili ana i ka lawelawe ʻana i ka hydrogen. Ke hoʻohālikelike ʻia me nā cell wahie methanol pololei (DMFCs), hōʻike nā DFAFC i kahi helu crossover wahie haʻahaʻa loa ma o nā membrane hoʻololi proton (PEMs). ʻO kēia ma muli o ka repulsion electrostatic ma waena o ka anion formate (HCOO⁻) a me nā hui waikawa sulfonic i loko o ka membrane, e ʻae ana i ka hoʻohana ʻana i ka wahie kiʻekiʻe (a hiki i ka 20 mol/L) e hoʻonui i ka nui o ka ikehu volumetric (4.4 kWh/dm³) me ka ʻole o ka pohō pono.
Ma ke ʻano electrochemical, ʻoi aku ka kiʻekiʻe o ka volta open-circuit theoretical (1.48 V) o nā DFAFC ma mua o nā hydrogen PEMFC (1.23 V) a me nā DMFC (1.20 V), e unuhi ana i ka mana hiki ke hoʻopuka nui aʻe. ʻAʻohe o ka molekole kalapona hoʻokahi i nā pilina CC, e hiki ai ke wikiwiki i ka oxidation kinetics a me ka hoʻokumu liʻiliʻi ʻana o nā CO intermediates e hoʻomake i nā mea hoʻoulu platinum. ʻOi aku ka paʻa o ka hana lōʻihi a ʻae pinepine i ka hoʻohana ʻana i nā mea hoʻoulu palladium ʻoi aku ka maikaʻi.
Eia kekahi, he haʻahaʻa ka ʻawaʻawa o ka waikawa formic (ua ʻāpono ʻia e ka FDA ma ke ʻano he mea hoʻohui meaʻai) a emi iki ka lapalapa ma mua o ka methanol, e hoʻomaʻalahi ana i ka halihali, ka mālama ʻana, a me nā kaʻina hana palekana no ka mea hoʻohana hope loa. ʻO ka mea nui, hiki ke hoʻohui ʻia ka waikawa formic ma o ka electroreduction CO₂, e hana ana i kahi loop carbon pani a hoʻolilo i nā DFAFC i ʻenehana koʻikoʻi no ka hoʻokō ʻana i ke kūlike ʻole o ke kalapona i nā mea uila lawe lima, nā lako mana liʻiliʻi, a me nā noi mamao ma waho o ka grid.
