Ma cell a formic acid
Kuthekera kwamalingaliro kwakusintha mphamvu zama mankhwala kukhala mphamvu zamagetsi m'maselo amafuta kumatha kufika 100%. Maperesenti, koma mpaka pano abwino kwambiri ndi haidrojeni - ali ndi mphamvu mpaka 60%, koma maselo amafuta opangidwa ndi formic acid ali ndi mwayi wofikira zongopeka 100%. Ndizotsika mtengo, zopepuka kwambiri kuposa zam'mbuyomu ndipo, mosiyana ndi mabatire wamba, zimapereka mwayi wogwira ntchito mosalekeza. M'pofunika kukumbukira kuti mphamvu ya otsika kuthamanga injini kuyaka mkati ndi za 20% -? akutero Dr. Hub. Chingerezi Andrzej Borodzinski from IPC PAS.
Selo yamafuta ndi chipangizo chomwe chimasinthira mphamvu zamakhemikhali kukhala magetsi. Pakalipano amapangidwa mwachindunji chifukwa cha kuyaka kwa mafuta pamaso pa zopangira zomwe zimagwiritsidwa ntchito pa anode ndi cathode ya selo. Cholepheretsa chachikulu kutchuka kwa ma cell a haidrojeni ndikusungidwa kwa haidrojeni. Vutoli latsimikizira kuti ndi lovuta kwambiri kuchokera ku luso lamakono ndipo silinathetsedwe ndi njira zokhutiritsa. Kupikisana ndi maselo a haidrojeni ndi maselo a methanol. Komabe, methanol palokha ndi chinthu chapoizoni, ndipo zinthu zomwe zimadya ziyenera kupangidwa pogwiritsa ntchito zida zodula za platinamu. Kuphatikiza apo, maselo a methanol ali ndi mphamvu zochepa ndipo amagwira ntchito pamtunda wokwera kwambiri, motero kutentha komwe kumakhala koopsa (pafupifupi madigiri 90).
Njira ina ndi ma cell amafuta a formic acid. Zomwe zimachitika zimapitilira kutentha, ndipo mphamvu ndi mphamvu zama cell ndizokwera kwambiri kuposa za methanol. Kuphatikiza apo, formic acid ndi chinthu chosavuta kusunga ndikunyamula. Komabe, kugwira ntchito mokhazikika kwa cell ya formic acid kumafuna chothandizira chogwira ntchito komanso cholimba. Chothandizira chomwe chinapangidwa ndi ife chili ndi ntchito yotsika kuposa zopangira zoyera za palladium zomwe zimagwiritsidwa ntchito mpaka pano. Komabe, kusiyanako kumatha pambuyo pa maola awiri akugwira ntchito. Kukhala bwino. Ngakhale kuti ntchito ya chothandizira choyera cha palladium ikupitirizabe kuchepa, yathu ndi yokhazikika, "akutero Dr. Borodzinsky.
Ubwino wa chothandizira chopangidwa pa IPC surfactant, chomwe chili chofunikira kwambiri pazachuma, ndikuti chimasungabe katundu wake pogwira ntchito mu asidi otsika a formic acid. Mtundu wa asidi wamtundu uwu ukhoza kupangidwa mosavuta mochuluka, kuphatikizapo kuchokera ku biomass, kotero mafuta a maselo atsopano angakhale otsika mtengo kwambiri. Biomass-derived formic acid ingakhale mafuta obiriwira. Zinthu zomwe zimachitika ndikutenga nawo gawo mumafuta amafuta ndi madzi ndi mpweya woipa. Yotsirizirayi ndi mpweya wowonjezera kutentha, koma biomass imapezeka kuchokera ku zomera zomwe zimayamwa pamene zikukula. Chotsatira chake, kupanga kwa formic acid kuchokera ku biomass ndi kugwiritsidwa kwake m'maselo sikungasinthe kuchuluka kwa carbon dioxide mumlengalenga. Chiwopsezo cha kuipitsidwa kwa chilengedwe ndi formic acid ndi chochepa.
Ma cell amafuta a Formic acid apeza ntchito zambiri. Kodi adzagwiritsa ntchito kwambiri zida zamagetsi zonyamulika? mafoni am'manja, laputopu, GPS. Zinthuzi zitha kukhazikitsidwanso ngati zopangira mphamvu zamagalimoto kuyambira pa njinga za olumala kupita panjinga zamagetsi ndi ma yacht.
Ku IPC PAS, kafukufuku tsopano akuyamba pa mabatire oyamba opangidwa kuchokera ku cell cell yamafuta acid. Asayansi amayembekezera kuti chitsanzo cha chipangizo chamalonda chiyenera kukhala chokonzeka m'zaka zingapo.
