Mphamvu ya haidrojeni ndi mbale ya graphite bipolar

Pakalipano, maiko ambiri ozungulira mbali zonse za kafukufuku watsopano wa haidrojeni ali pachimake, zovuta zaumisiri kukwera kuti zigonjetse. Ndi kukula kosalekeza kwa kukula kwa kupanga mphamvu za haidrojeni ndikusungirako ndi zoyendera, mtengo wa mphamvu ya haidrojeni ulinso ndi malo akulu ochepera. Kafukufuku akuwonetsa kuti mtengo wonse wamakampani opanga mphamvu ya hydrogen ukuyembekezeka kutsika ndi theka pofika chaka cha 2030. Malinga ndi lipoti lomwe linatulutsidwa pamodzi ndi International Hydrogen Energy Commission ndi McKinsey, mayiko oposa 30 ndi madera atulutsa mapu a chitukuko cha mphamvu ya hydrogen, ndipo ndalama zapadziko lonse lapansi zamapulojekiti amagetsi a haidrojeni zidzafika madola 300 biliyoni aku US pofika 2030

Ma cell amafuta a haidrojeni amapangidwa ndi ma cell angapo amafuta omwe amasungidwa motsatizana.The bipolar mbale ndi nembanemba elekitirodi MEA anapiringizana alternately, ndi zisindikizo ophatikizidwa pakati pa monoma aliyense. Akakanikizidwa ndi mbale zakutsogolo ndi zakumbuyo, amamangidwa ndikumangidwa ndi zomangira kuti apange stack ya cell ya hydrogen.

Bipolar mbale ndi nembanemba elekitirodi MEA amapinizidwa mosinthana, ndipo zisindikizo ophatikizidwa pakati pa monoma iliyonse. Pambuyo popanikizidwa ndi mbale zakutsogolo ndi zakumbuyo, zimamangiriridwa ndikumangidwa ndi zomangira kuti zipangitse hydrogen fuel cell stack.Pakali pano, ntchito yeniyeni ndiyoBipolar mbale yopangidwa ndi graphite yokumba.Bipolar mbale yopangidwa ndi zinthu zotere imakhala ndi ma conductivity abwino komanso kukana dzimbiri. Komabe, chifukwa cha zofunikira kuti mpweya wothina wa mbale ya bipolar, kupanga kumafunikira njira zambiri zopangira monga utomoni wa utomoni, carbonization, graphitization ndi kukonzedwanso kotsatira kumunda, kotero kupanga njira yopangira ndizovuta komanso mtengo wake ndi wokwera kwambiri. kukhala chinthu chofunikira choletsa kugwiritsa ntchito mafuta cell.

Proton kusintha kwa membranemafuta cell (PEMFC) amatha kusintha mwachindunji mphamvu yamankhwala kukhala mphamvu yamagetsi m'njira ya isothermal ndi electrochemical. Sizochepa ndi Carnot cycle, imakhala ndi mphamvu zambiri zosinthira mphamvu (40% ~ 60%), ndipo ndi yaukhondo komanso yopanda kuipitsa (zopangidwa makamaka ndi madzi). Imawerengedwa kuti ndiyo njira yoyamba yoperekera mphamvu zamagetsi m'zaka za zana la 21. Monga kulumikiza chigawo chimodzi cha maselo amodzi mu PEMFC okwana, bipolar mbale makamaka amasewera ntchito kudzipatula kugwirizana mpweya pakati pa maselo, kugawira mafuta ndi okosijeni, kuthandiza nembanemba elekitirodi ndi kulumikiza maselo limodzi mndandanda kupanga dera zamagetsi.
