aside formike Utunyangingo twa lisansi
Aside formike ikoreshwa kandi nk'amavuta mu turemangingo twa aside formike (DFAFCs). Muri utwo turemangingo twa lisansi, aside formike ikora nk'amavuta, ikora ogisijeni kuri anode kugira ngo irekure electron kandi ikore ingufu z'amashanyarazi. DFAFCs zitanga ibyiza nko kuba ingufu nyinshi n'ubushyuhe buke, zikagira amahirwe yo gukoreshwa mu bikoresho bito by'ikoranabuhanga n'amasoko y'amashanyarazi agendanwa.

Ku bijyanye na Zibo Anhao Chemical Co., Ltd.

Ibyiza by'uturemangingo twa aside formic (DFAFCs)
Uturemangingo twa aside formike (DFAFCs) twigaragaza nk'ikoranabuhanga ritanga icyizere cyo guhindura ingufu za elegitoroniki, ritanga uruvange rudasanzwe rw'umutekano mwiza, imikorere myiza idasanzwe, n'imikorere ifatika ikemura imbogamizi zikomeye ku buryo bwo guhindura ibintu bushingiye kuri hydrogen na methanol.
Nk’amavuta y’amazi mu bushyuhe bw’icyumba no mu muvuduko w’ikirere, aside formike (HCOOH) ikuraho gukenera gukandamizwa cyane cyangwa kubika ibintu bidafite umuvuduko mwinshi, bigabanya cyane ikiguzi cy’ibikorwa remezo n’ingaruka z’umutekano zijyanye no gucunga hydrogen. Ugereranyije n’uturemangingo twa lisansi twa methanoli (DMFCs), DFAFC zigaragaza igipimo cyo kunyuramo lisansi kiri hasi cyane binyuze mu membrane za proton exchange (PEMs). Ibi biterwa no guhumeka kwa electrostatic hagati ya anion ya formate (HCOO⁻) n’amatsinda ya aside sulfonic mu membrane, bigatuma hakoreshwa lisansi ifite imbaraga nyinshi (kugeza kuri mol/L 20) kugira ngo hongerwe ubucucike bw’ingufu (4.4 kWh/dm³) nta gutakaza ubushobozi.
Mu bijyanye n'amashanyarazi, DFAFC zifite voltage iri hejuru y'icyerekezo (1.48 V) kurusha PEMFC za hydrogen (1.23 V) na DMFC (1.20 V), bigatuma habaho imbaraga nyinshi. Molekile ya karuboni imwe ibura imigozi ya CC, bigatuma kinetiki yihuta ya oxidation ndetse no kugabanuka gato kwa CO intermediates zihumanya platinum catalysts. Ibi bituma habaho imikorere ihamye kandi irambye kandi akenshi yemerera ikoreshwa rya catalysts zishingiye kuri palladium zihendutse.
Byongeye kandi, aside formike ni uburozi buke (yemejwe na FDA nk'inyongeramusaruro ku biribwa) kandi ntishobora gushya cyane kurusha methanol, byoroshya ubwikorezi, ububiko, n'amabwiriza y'umutekano ku bakoresha. Igishimishije ni uko aside formike ishobora gukorwa mu buryo burambye binyuze mu kugabanya CO₂ electroreduction, bigatuma habaho urujya n'uruza rw'ingufu za karuboni zifunganye kandi bigatuma DFAFCs iba ikoranabuhanga ry'ingenzi ryo kugera ku igabanuka rya karuboni mu bikoresho by'ikoranabuhanga bitwarwa, amashanyarazi mato, no mu bikorwa biri kure bitajyanye n'umuyoboro w'amashanyarazi.
