Mfundo ya galimoto ya hydrogen mafuta cell ndi chiyani?

Selo yamafuta ndi mtundu wa chipangizo chopangira mphamvu, chomwe chimasintha mphamvu zamachemical mumafuta kukhala mphamvu yamagetsi ndi redox reaction of oxygen kapena ma oxidants ena. Mafuta omwe amapezeka kwambiri ndi haidrojeni, omwe amatha kumveka ngati momwe madzi amachitira electrolysis kupita ku haidrojeni ndi mpweya.

Mosiyana ndi rocket, hydrogen mafuta cell samatulutsa mphamvu ya kinetic chifukwa cha chiwawa cha hydrogen ndi kuyaka kwa okosijeni, koma imatulutsa mphamvu yaulere ya Gibbs mu haidrojeni kudzera mu chipangizo chothandizira. Mfundo yake yogwira ntchito ndi yakuti haidrojeni imawonongeka kukhala ma electron ndi ma hydrogen ions (maprotoni) kudzera mu chothandizira (nthawi zambiri platinamu) mu electrode yabwino ya selo yamafuta. Mapulotoni amafika pa electrode yoyipa kudzera pa membrane wosinthira wa proton ndikumachita ndi mpweya kupanga madzi ndi kutentha. Ma elekitironi ofanana amayenda kuchokera ku electrode yabwino kupita ku electrode yoyipa kudzera mudera lakunja kuti apange mphamvu yamagetsi. Ilibe botolo lamafuta okwana pafupifupi 40% pa injini yamafuta, ndipo mphamvu ya cell yamafuta a hydrogen imatha kufika pafupifupi 60%.

Zaka zingapo zapitazo, mphamvu ya haidrojeni imatchedwa "mawonekedwe apamwamba" a magalimoto atsopano amphamvu chifukwa cha ubwino wake wa kuipitsidwa kwa zero, mphamvu zowonjezera, hydrogenation mofulumira, zonse ndi zina zotero. Komabe, chiphunzitso chaukadaulo cha hydrogen mafuta cell ndi changwiro, koma kupita patsogolo kwa mafakitale ndikobwerera m'mbuyo. Chimodzi mwazovuta zazikulu za kukwezedwa kwake ndikuwongolera mtengo. Izi sizikuphatikizapo mtengo wa galimoto yokha, komanso mtengo wa hydrogen kupanga ndi kusunga.

Kukula kwa magalimoto amafuta a hydrogen kumadalira pakupanga zida zamafuta a haidrojeni monga kupanga ma hydrogen, kusungirako ma hydrogen, mayendedwe a hydrogen ndi hydrogenation. Mosiyana ndi ma tramu angwiro, omwe amatha kulipiritsa pang'onopang'ono kunyumba kapena kukampani, magalimoto a haidrojeni amatha kulipiritsa pa station ya hydrogenation, chifukwa chake kufunikira kwa malo othamangitsira ndikofunikira kwambiri. Popanda makina a hydrogenation wathunthu, chitukuko cha magalimoto a haidrojeni sizingatheke.
