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 ndi International Hydrogen Energy Commission ndi McKinsey, mayiko opitilira 30 ndi zigawo zatulutsa njira yachitukuko champhamvu ya hydrogen, ndipo ndalama zapadziko lonse lapansi pantchito zamphamvu za hydrogen zidzafika 300 biliyoni US dollars pofika 2030.

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

The bipolar mbale ndi nembanemba elekitirodi MEA ndi anapiringizika alternately, 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 ndiyombale ya bipolar 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 bipolar, kupanga ndondomeko amafuna njira zambiri kupanga monga utomoni impregnation, carbonization, graphitization ndi wotsatira otaya kumunda processing, kotero kupanga ndondomeko zovuta ndipo mtengo wake ndi wokwera kwambiri, Iwo wakhala chinthu chofunika kuletsa 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 yosinthira mphamvu (40% ~ 60%), ndipo imakhala 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.
