Kodi mfundo ya galimoto ya hydrogen fuel cell ndi iti?

Selo yamafuta ndi mtundu wa chipangizo chopangira magetsi, chomwe chimasintha mphamvu ya mankhwala mu mafuta kukhala mphamvu yamagetsi pogwiritsa ntchito redox reaction ya mpweya kapena ma oxidant ena. Mafuta ofala kwambiri ndi hydrogen, omwe amatha kumveka ngati reverse reaction ya electrolysis ya madzi ku hydrogen ndi oxygen.

Mosiyana ndi roketi, maselo amafuta a haidrojeni sapanga mphamvu ya kinetic kudzera mu mphamvu yamphamvu ya haidrojeni ndi okosijeni, koma amatulutsa mphamvu ya Gibbs mu haidrojeni kudzera mu chipangizo chothandizira. Mfundo yake yogwirira ntchito ndi yakuti haidrojeni imasungunuka kukhala ma elekitironi ndi ma ayoni a haidrojeni (ma protoni) kudzera mu chothandizira (nthawi zambiri platinamu) mu elekitironi yabwino ya selo yamafuta. Ma protoni amafika pa elekitironi yoyipa kudzera mu nembanemba yosinthira ya selo yamafuta ndipo amachitapo kanthu ndi mpweya kuti apange madzi ndi kutentha. Ma elekitironi ofanana amayenda kuchokera ku elekitironi yabwino kupita ku elekitironi yoyipa kudzera mu dera lakunja kuti apange mphamvu yamagetsi. Alibe vuto la kutentha kwa pafupifupi 40% pa injini yamafuta, ndipo mphamvu ya maselo amafuta a haidrojeni imatha kufika mosavuta pa 60%.

Kale kwambiri, mphamvu ya haidrojeni inkadziwika kuti ndi "mtundu wapamwamba kwambiri" wa magalimoto atsopano amphamvu chifukwa cha ubwino wake wopanda kuipitsa, mphamvu zongowonjezwdwanso, hydrogenation yachangu, mphamvu zonse ndi zina zotero. Komabe, chiphunzitso chaukadaulo cha maselo amafuta a haidrojeni ndi changwiro, koma kupita patsogolo kwa mafakitale kwabwerera m'mbuyo kwambiri. Chimodzi mwa zovuta zazikulu pakukweza kwake ndikuwongolera ndalama. Izi sizikuphatikizapo mtengo wa galimoto yokha, komanso mtengo wopanga ndi kusunga haidrojeni.

Kupanga magalimoto a haidrojeni kumadalira pakupanga zinthu zopangira mafuta a haidrojeni monga kupanga haidrojeni, kusungira haidrojeni, mayendedwe a haidrojeni ndi hydrogenation. Mosiyana ndi ma tram oyera, omwe amatha kulipidwa pang'onopang'ono kunyumba kapena pakampani, magalimoto a haidrojeni amatha kulipidwa kokha pa siteshoni ya hydrogenation, kotero kufunikira kwa siteshoni yolipirira ndikofunika kwambiri. Popanda netiweki yonse ya hydrogenation, chitukuko cha makampani opanga magalimoto a haidrojeni n'kosatheka.
