I-Formic Acid Amaseli Kaphethiloli
I-formic acid isetshenziswa futhi njengophethiloli kumaseli kaphethiloli e-formic acid aqondile (ama-DFAFC). Kula maseli kaphethiloli, i-formic acid isebenza njengophethiloli, idlula ekusabeleni kwe-oxidation ku-anode ukuze ikhulule ama-electron futhi ikhiqize amandla kagesi. Ama-DFAFC anikeza izinzuzo ezifana nokuminyana kwamandla aphezulu kanye namazinga okushisa aphansi okusebenza, ephethe izinhlelo zokusebenza ezingaba khona ezithembisayo kumadivayisi amancane kagesi kanye nemithombo yamandla ephathekayo.

Izinzuzo zamaseli kaphethiloli e-Formic Acid (ama-DFAFC)
Amaseli kaphethiloli e-formic acid aqondile (ama-DFAFC) avelele njengobuchwepheshe bokuguqula amandla e-electrochemical obuthembisayo kakhulu, obunikeza inhlanganisela eyingqayizivele yokuphepha okuphezulu, ukusebenza kahle okumangalisayo, kanye nokusebenza okusebenzayo okubhekana nemikhawulo ebalulekile yezinye izindlela ezisekelwe ku-hydrogen kanye ne-methanol.
Njengophethiloli owuketshezi ekushiseni kwegumbi kanye nomfutho womoya, i-formic acid (HCOOH) isusa isidingo sokucindezela okuphezulu noma isitoreji se-cryogenic, inciphisa kakhulu izindleko zengqalasizinda kanye nezingozi zokuphepha ezihlobene nokuphathwa kwe-hydrogen. Uma kuqhathaniswa namaseli kaphethiloli e-methanol aqondile (DMFCs), ama-DFAFC abonisa izinga eliphansi kakhulu lokuwela uphethiloli ngokusebenzisa ama-membrane okushintshana kwe-proton (PEMs). Lokhu kungenxa yokuxoshwa kwe-electrostatic phakathi kwe-formate anion (HCOO⁻) kanye namaqembu e-sulfonic acid ku-membrane, okuvumela ukusetshenziswa kukaphethiloli ogxile kakhulu (kufika ku-20 mol/L) ukukhulisa ubuningi bamandla e-volumetric (4.4 kWh/dm³) ngaphandle kokulahlekelwa ukusebenza kahle.
Ngokwe-electrochemical, ama-DFAFC ane-voltage ephezulu ye-theoretical open-circuit (1.48 V) kunama-hydrogen PEMFC (1.23 V) nama-DMFC (1.20 V), okuhumusha amandla aphumayo aphezulu. I-molecule ye-single-carbon ayinazo izibopho ze-CC, okuvumela i-oxidation kinetics esheshayo kanye nokwakheka okuncane kwama-CO intermediates anobuthi kuma-catalyst e-platinum. Lokhu kuphumela ekusebenzeni okuzinzile, kwesikhathi eside futhi kuvame ukuvumela ukusetshenziswa kwama-catalyst asekelwe ku-palladium angabizi kakhulu.
Ngaphezu kwalokho, i-formic acid inobuthi obuphansi (ivunyelwe yi-FDA njengesithasiselo sokudla) futhi ayishisi kakhulu kune-methanol, okwenza kube lula ukuthutha, ukugcina, kanye nezinqubo zokuphepha zabasebenzisi bokugcina. Okuphawulekayo ukuthi i-formic acid ingakhiwa ngendlela eqhubekayo nge-CO₂ electroreduction, okudala i-closed carbon loop futhi yenze ama-DFAFC abe ubuchwepheshe obubalulekile bokufeza ukungathathi hlangothi kwe-carbon kuma-elekthronikhi aphathekayo, izinsiza zamandla ezincane, kanye nezinhlelo zokusebenza ezikude ezingaphandle kwegridi.
