I-Formic Acid Iiseli zeFuel
I-asidi ye-formic ikwasetyenziswa njenge-fuel kwii-direct formic acid fuel cells (ii-DFAFC). Kwezi fuel cells, i-asidi ye-formic isebenza njenge-fuel, ifumana i-oxidation reaction kwi-anode ukuze ikhuphe ii-electron kwaye ivelise amandla ombane. Ii-DFAFCs zibonelela ngeenzuzo ezifana noxinano lwamandla aphezulu kunye namaqondo obushushu aphantsi okusebenza, zibambe usetyenziso oluthembisayo kwizixhobo ezincinci ze-elektroniki kunye nemithombo yamandla ephathekayo.

Iingenelo zeeFomic Acid Fuel Cells (iiDFAFC)
Iiseli ze-fuel ze-asidi ezithe ngqo (ii-DFAFC) zibonakala njengeteknoloji yokuguqula amandla e-electrochemical ethembisayo kakhulu, enika indibaniselwano eyahlukileyo yokhuseleko oluphezulu, ukusebenza kakuhle okugqwesileyo, kunye nokusebenza okusebenzayo okujongana nemida ebalulekileyo yeendlela ezisekwe kwi-hydrogen kunye ne-methanol.
Njenge-fuel engamanzi kubushushu begumbi kunye noxinzelelo lomoya, i-formic acid (HCOOH) isusa imfuneko yoxinzelelo oluphezulu okanye ugcino lwe-cryogenic, inciphisa kakhulu iindleko zeziseko kunye nemingcipheko yokhuseleko enxulumene nokuphathwa kwe-hydrogen. Xa kuthelekiswa nee-direct methanol fuel cells (DMFCs), ii-DFAFCs zibonisa izinga eliphantsi kakhulu le-fuel crossover ngokusebenzisa ii-proton exchange membranes (PEMs). Oku kungenxa yokugxothwa kwe-electrostatic phakathi kwe-formate anion (HCOO⁻) kunye namaqela e-sulfonic acid kwi-membrane, okuvumela ukusetyenziswa kwe-fuel ene-concentration ephezulu (ukuya kuthi ga kwi-20 mol/L) ukwandisa uxinano lwamandla e-volumetric (4.4 kWh/dm³) ngaphandle kokulahlekelwa kokusebenza kakuhle.
Ngokwe-electrochemicals, ii-DFAFCs zine-voltage ephezulu ye-theoretical open-circuit (1.48 V) kune-hydrogen PEMFCs (1.23 V) kunye nee-DMFCs (1.20 V), nto leyo ethetha ukuba amandla aphuma ngamandla aphezulu. Imolekyuli ye-single-carbon ayinazo ii-CC bonds, nto leyo evumela i-oxidation kinetics ekhawulezayo kunye nokwakheka okuncinci kwee-CO intermediates ezityhefa ii-platinum catalysts. Oku kubangela ukusebenza okuzinzileyo, okuhlala ixesha elide kwaye kudla ngokuvumela ukusetyenziswa kwee-catalysts ezisekelwe kwi-palladium ezingabizi kakhulu.
Ngaphezu koko, i-formic acid ayinabungozi kangako (ivunyiwe yi-FDA njengesongezo sokutya) kwaye ayitshisi kakhulu kune-methanol, nto leyo eyenza kube lula ukuthutha, ukugcina, kunye neenkqubo zokhuseleko zabasebenzisi bokugqibela. Okubalulekileyo kukuba, i-formic acid inokwenziwa ngendlela ezinzileyo nge-CO₂ electroreduction, idale i-closed carbon loop kwaye yenze ii-DFAFC zibe bubuchwepheshe obubalulekileyo bokufezekisa ukungakhethi cala kwekhabhoni kwii-elektroniki eziphathwayo, izixhobo zamandla ezincinci, kunye nezicelo ezikude ezingaphandle kwegridi.
