Formic Acid Cov Roj Hmab
Cov kua qaub Formic kuj tseem siv ua roj hauv cov roj hluav taws xob ncaj qha (DFAFCs). Hauv cov roj hluav taws xob no, cov kua qaub formic ua haujlwm ua roj, dhau los ntawm kev sib xyaw ua ke ntawm qhov anode los tso cov hluav taws xob thiab tsim lub zog hluav taws xob. DFAFCs muaj cov txiaj ntsig xws li lub zog ceev ceev thiab qhov kub ua haujlwm qis, tuav cov ntawv thov zoo hauv cov khoom siv hluav taws xob me me thiab cov chaw siv hluav taws xob nqa tau.

Cov txiaj ntsig ntawm Formic Acid Fuel Cells (DFAFCs)
Cov roj teeb formic acid ncaj qha (DFAFCs) sawv cev rau qhov kev siv tshuab hloov pauv hluav taws xob zoo heev, muab kev sib xyaw ua ke ntawm kev nyab xeeb zoo tshaj plaws, kev ua haujlwm zoo tshaj plaws, thiab kev ua haujlwm tau zoo uas daws cov teeb meem tseem ceeb ntawm cov kev xaiv siv hydrogen thiab methanol.
Ua ib yam roj ua kua ntawm chav tsev kub thiab qhov siab ntawm huab cua, formic acid (HCOOH) tshem tawm qhov xav tau kev nias siab lossis kev cia khoom cryogenic, txo cov nqi tsim kho vaj tse thiab kev pheej hmoo kev nyab xeeb cuam tshuam nrog kev tuav hydrogen. Piv rau cov roj methanol ncaj qha (DMFCs), DFAFCs qhia txog tus nqi hla roj qis dua los ntawm cov txheej txheem pauv proton (PEMs). Qhov no yog vim muaj electrostatic repulsion ntawm formate anion (HCOO⁻) thiab cov pab pawg sulfonic acid hauv daim nyias nyias, tso cai rau kev siv roj siab (txog li 20 mol / L) kom ua kom muaj zog ntau tshaj plaws (4.4 kWh / dm³) yam tsis muaj kev poob qis.
Nyob rau hauv electrochemical, DFAFCs muaj qhov hluav taws xob qhib hluav taws xob siab dua (1.48 V) dua li ob qho tib si hydrogen PEMFCs (1.23 V) thiab DMFCs (1.20 V), txhais tau tias muaj peev xwm tso zis hluav taws xob ntau dua. Lub molecule ib leeg-carbon tsis muaj CC bonds, ua rau oxidation kinetics sai dua thiab tsawg kawg nkaus tsim ntawm CO intermediates uas lom platinum catalysts. Qhov no ua rau muaj kev ruaj khov dua, kev ua haujlwm ntev dua thiab feem ntau tso cai rau kev siv cov catalysts raws li palladium uas pheej yig dua.
Ntxiv mus, cov kua qaub formic tsis muaj tshuaj lom (FDA pom zoo ua cov khoom noj khoom haus ntxiv) thiab tsis yooj yim hlawv dua li methanol, ua rau kev thauj mus los, kev khaws cia, thiab cov txheej txheem kev nyab xeeb rau cov neeg siv kawg yooj yim dua. Qhov tseem ceeb, cov kua qaub formic tuaj yeem tsim tau ruaj khov los ntawm CO₂ electroreduction, tsim kom muaj lub voj voog carbon kaw thiab ua rau DFAFCs yog cov thev naus laus zis tseem ceeb rau kev ua tiav cov pa roj carbon neutrality hauv cov khoom siv hluav taws xob nqa tau, cov khoom siv hluav taws xob me me, thiab cov ntawv thov tawm ntawm lub network deb.
