Asidhi yeFormic Masero emafuta
Asidhi yeFormic inoshandiswawo semafuta mumasero emafuta eFormic acid (DFAFCs). Mumasero aya emafuta, formic acid inoshanda semafuta, ichipinda mu oxidation reaction pa anode kuti ibudise maerekitironi uye igadzire simba remagetsi. MaDFAFC ane zvakanakira zvakaita sehuwandu hwesimba rakawanda uye tembiricha shoma yekushanda, achichengetedza mikana yekushandisa mumidziyo midiki yemagetsi uye masosi emagetsi anotakurika.

Mabhenefiti eFormic Acid Fuel Cells (DFAFCs)
Masero emafuta emhando ye Direct formic acid (DFAFCs) anoonekwa se tekinoroji inovimbisa zvikuru yekushandura simba remagetsi, ichipa musanganiswa wakasarudzika wekuchengetedza kwakanyanya, kushanda zvakanaka, uye kushanda zvakanaka kunobata miganhu yakakosha yesarudzo dzehydrogen ne methanol.
Semafuta emvura patembiricha yemumba uye kumanikidzwa kwemhepo, formic acid (HCOOH) inobvisa kudiwa kwekumanikidzwa kwakanyanya kana kuchengetwa kwe cryogenic, zvichideredza zvakanyanya mari yezvivakwa uye njodzi dzekuchengetedza dzine chekuita nekubata hydrogen. Zvichienzaniswa ne direct methanol fuel cells (DMFCs), maDFAFC anoratidza mwero wepasi wemafuta kuburikidza neproton exchange membranes (PEMs) wakaderera zvikuru. Izvi zvinokonzerwa nekudzoserwa kwemagetsi pakati peformate anion (HCOO⁻) nemapoka esulfonic acid ari mumembrane, zvichibvumira kushandiswa kwemafuta ane huwandu hwakawanda (kusvika ku20 mol/L) kuwedzera huwandu hwesimba revolumetric (4.4 kWh/dm³) pasina kurasikirwa kwekushanda zvakanaka.
Panyaya yemagetsi, maDFAFC ane voltage yakakwira ye theoretical open-circuit (1.48 V) kupfuura ese ari maviri hydrogen PEMFCs (1.23 V) uye DMFCs (1.20 V), zvichireva kuti simba rinobuda zvakanyanya. Molekyuru imwe chete yekabhoni haina maCC bonds, zvichiita kuti oxidation kinetics ikurumidze uye kuumbwa kushoma kweCO intermediates dzinouraya platinum catalysts. Izvi zvinoita kuti pave nekushanda kwakasimba uye kwenguva refu uye zvinowanzo bvumidza kushandiswa kwepalladium-based catalysts inodhura zvishoma.
Uyezve, formic acid haina chepfu yakawanda (FDA-inotenderwa sechikafu chinowedzera) uye haibati moto zvakanyanya kupfuura methanol, zvichiita kuti kutakurwa, kuchengetwa, uye kuchengetedzeka kwemushandisi zvive nyore. Zvakakosha kuti formic acid inogona kugadzirwa nenzira inochengetedza kuburikidza neCO₂ electroreduction, zvichigadzira closed carbon loop uye zvichiita kuti DFAFCs ive tekinoroji inokosha yekuwana carbon neutral mumagetsi anotakurika, magetsi madiki, uye mashandisirwo ari kure emagetsi.
