Hydrogen li roj rau pa tsheb

Txawm li cas los, hydrogen xyaw rau hauv dog dig tsheb tsis heev muaj kev nyab xeeb nyob rau hauv lub lag luam, tshwj xeeb tshaj yog rau cov hydrogen cia thiab nws cov mov mus rau lub combustion chamber. Tom qab tag nrho cov paub pib Science News for KIDS kawm ntawv kawm los ntawm reacting hydrogen nrog rau oxygen ntaub ntawv xws compound raws li ib tug oxyhydrogen roj uas yog heev. Hais tias qhov no yog tsis los ua ib tug tag nrho-fledged hydrogen tsheb. Txawm tias British zaum tsis xav li ntawd.

Lawv siv scientific tau tsim ib tug txheej txheem tshiab thiab technology. Nyob rau nws, hydrogen yog muaj nyob rau hauv ib tug tshwj xeeb lub thawv (tank) uas nws ntau thiab tsawg pab yog tsis ntau tshaj li 3-4 microns, tab sis qhov no cov ntaub ntawv roj hlwb muaj ib tug ntxeem tau qauv. Ib tug hydrogen yog noj mus rau lawv nyob hauv cov ntshiab daim ntawv thiab nyob rau hauv daim ntawv ntawm cov hydrides. Thiab nrog me ntsis cua kub ntawm cov roj hlwb (tsiav tshuaj) pib mus rau sawv tawm los ntawm lub micropore hydrogen. Yog li, zaum tau ua tau zoo nyob rau hauv kev tsim ib tug ntau tseeb qauv ntawm lub hydrogen engine, uas nyob rau qhov kev tsim nyog fine-tuning yog heev muaj peev xwm rau loj ntau lawm thiab yog zaum nyob rau hauv kev sib tw nrog internal combustion xyaw. Tab sis muaj ib tug xov tooj ntawm cov teeb meem muaj feem xyuam rau cov kev sab. Firstly nws yuav tsum tau qhov yuav tsum tau rau sai cua sov ntawm cov roj cell (tsiav tshuaj) thiab tib lub peev xwm los hloov hydrogen los ntawm txhua capsule nyob rau hauv lub hwj huam mov system lub cev muaj zog.

Txawm li cas los, nyob rau hauv thawj kauj ruam, zaum yuav siv no technology nyob rau hauv cov pa tsheb nrog nrog combustion xyaw. Ua li no nyob rau hauv lub tsheb yuav tsum muab tso rau ib tug ntxiv tank nrog hydrogen xws tsiav tshuaj. Ib tug hydrogen gas nws tus kheej yog tsis tseem ceeb roj thiab cov koom haum pab. Cov kev twb siv nyob rau hauv kev sib hwm ntawm Bioethanol nyob rau hauv ib tug xov tooj ntawm lub teb chaws. Ib yam li ntawd, ib feem los ntawm nrog hydrogen nyob rau hauv cov roj sib tov yuav tsum maj mam nce mus txog rau thaum cov roj yog kiag li hloov. Qhov no pub rau ib tug me me kev cai rau siv niaj hnub tsheb tsis muaj kev txwv, thiab los ntawm maj ua rau tus xov tooj ntawm hydrogen tsheb mus npaj thiab tsim kom muaj lwm yam kev infrastructure. Cov ntsuam xyuas thawj zaug ntawm lub tsheb yog teem twb rau hauv thawj ib nrab ntawm 2012.
