Mphamvu ya haidrojeni ndi mbale ya bipolar ya graphite

Pakadali pano, mayiko ambiri ozungulira mbali zonse za kafukufuku watsopano wa haidrojeni akuyamba, mavuto aukadaulo akufunika kuthana nawo. Chifukwa cha kukula kosalekeza kwa kupanga mphamvu ya haidrojeni ndi zomangamanga zosungira ndi zoyendera, mtengo wa mphamvu ya haidrojeni ulinso ndi malo akuluakulu oti utsike. Kafukufuku akuwonetsa kuti mtengo wonse wa unyolo wamakampani opanga mphamvu ya haidrojeni ukuyembekezeka kutsika ndi theka pofika chaka cha 2030. Malinga ndi lipoti lomwe linatulutsidwa pamodzi ndi Hydrogen Energy Commission yapadziko lonse ndi McKinsey, mayiko ndi madera opitilira 30 atulutsa njira yopangira mphamvu ya haidrojeni, ndipo ndalama zomwe dziko lonse limagwiritsa ntchito m'mapulojekiti a mphamvu ya haidrojeni zidzafika madola 300 biliyoni aku US pofika chaka cha 2030.

Maselo amafuta a haidrojeni amapangidwa ndi maselo ambiri amafuta omwe amaikidwa motsatizana.Bipolar plate ndi membrane electrode MEA zimalumikizana motsatizana, ndipo zomangira zimayikidwa pakati pa monomer iliyonse. Pambuyo pokanikizidwa ndi mbale zakutsogolo ndi zakumbuyo, zimamangiriridwa ndi zomangira kuti zipange hydrogen fuel cell stack.

Mbale ya bipolar ndi membrane electrode MEA zimalumikizana motsatizana, ndipo zisindikizo zimayikidwa pakati pa monomer iliyonse. Pambuyo pokanikizidwa ndi mbale zakutsogolo ndi zakumbuyo, zimamangiriridwa ndi zomangira kuti zipange hydrogen fuel cell stack. Pakadali pano, ntchito yeniyeni ndimbale yozungulira yopangidwa ndi graphite yopangidwa.Mbale ya bipolar yopangidwa ndi zinthu zamtunduwu ili ndi mphamvu yabwino yoyendetsera mpweya komanso kukana dzimbiri. Komabe, chifukwa cha zofunikira kuti mbale ya bipolar ikhale yolimba, njira yopangira imafunika njira zambiri zopangira monga kuyika resin, carbonization, graphitization ndi kukonza malo oyenda, kotero njira yopangira ndi yovuta ndipo mtengo wake ndi wokwera kwambiri, Yakhala chinthu chofunikira kwambiri choletsa kugwiritsa ntchito fuel cell.

Nembanemba yosinthira mapulotoniSelo yamafuta (PEMFC) imatha kusintha mphamvu ya mankhwala kukhala mphamvu yamagetsi mwachindunji m'njira ya isothermal ndi electrochemical. Sichimalepheretsedwa ndi kayendedwe ka Carnot, chili ndi mphamvu zambiri zosinthira mphamvu (40% ~ 60%), ndipo ndi yoyera komanso yopanda kuipitsa (mankhwalawa ndi madzi ambiri). Imaonedwa kuti ndi njira yoyamba yoperekera mphamvu yogwira ntchito komanso yoyera m'zaka za m'ma 2000. Monga gawo lolumikizira maselo amodzi mu PEMFC stack, bipolar plate imagwira ntchito makamaka yolekanitsa mpweya pakati pa maselo, kugawa mafuta ndi okosijeni, kuthandizira membrane electrode ndikulumikiza maselo amodzi motsatizana kuti apange magetsi.
