Roj hlwb tuaj yeem muab faib uaproton pauv membraneroj hlwb (PEMFC) thiab ncaj qha methanol roj hlwb raws li cov khoom siv electrolyte thiab roj siv
(DMFC), phosphoric acid roj cell (PAFC), molten carbonate roj cell (MCFC), khoom oxide roj cell (SOFC), alkaline roj cell (AFC), thiab lwm yam. Piv txwv li, proton exchange membrane roj hlwb (PEMFC) feem ntau cia siab rau. ntawmproton pauv membraneHloov cov proton nruab nrab, alkaline roj hlwb (AFC) siv alkaline dej-raws li electrolyte xws li poov tshuaj hydroxide tov li proton hloov nruab nrab, thiab lwm yam. Tsis tas li ntawd, raws li qhov kub thiab txias, roj hlwb tuaj yeem muab faib ua cov roj kub kub thiab tsis kub. roj hlwb, cov qub feem ntau suav nrog cov khoom siv roj oxide (SOFC) thiab cov roj carbon monoxide molten (MCFC), tom kawg suav nrog proton txauv membrane roj hlwb (PEMFC), direct methanol roj hlwb. (DMFC), alkaline roj hlwb (AFC), phosphoric acid roj hlwb (PAFC), thiab lwm yam.
Proton pauv membraneroj hlwb (PEMFC) siv dej-raws li acidic polymer membranes raws li lawv cov electrolytes. PEMFC cov hlwb yuav tsum ua haujlwm nyob rau hauv cov pa ntshiab hydrogen vim lawv qhov kub thiab txias (qis dua 100 ° C) thiab siv cov hlau electrodes (platinum raws li electrodes). Piv nrog rau lwm cov roj hlwb, PEMFC muaj qhov zoo ntawm kev ua haujlwm qis, kev pib ceev ceev, siab zog ceev, tsis muaj corrosive electrolyte thiab lub neej ua haujlwm ntev. Yog li, nws tau dhau los ua cov thev naus laus zis tseem ceeb tam sim no siv rau roj tsheb tsheb, tab sis kuj yog ib feem siv rau cov khoom siv txav tau thiab nyob ruaj khov. Raws li E4 Tech, PEMFC roj cell xa khoom yuav tsum ncav cuag 44,100 units hauv 2019, suav txog 62% ntawm lub ntiaj teb sib koom; Qhov kwv yees nruab muaj peev xwm ncav cuag 934.2MW, suav txog 83% ntawm lub ntiaj teb kev faib ua feem.
Cov roj hlwb siv cov tshuaj electrochemical los hloov cov tshuaj siv hluav taws xob los ntawm cov roj (hydrogen) ntawm cov anode thiab oxidant (oxygen) ntawm cathode rau hauv hluav taws xob los tsav tag nrho lub tsheb. Tshwj xeeb, cov ntsiab lus tseem ceeb ntawm cov roj hlwb muaj xws li lub cev muaj zog, lub zog pabcuam thiab lub cev muaj zog; Ntawm lawv, lub cav system feem ntau suav nrog lub cav tsim los ntawm hluav taws xob reactor, tsheb hydrogen cia system, cua txias system thiab DCDC voltage converter. Lub reactor yog qhov tseem ceeb tshaj plaws. Nws yog qhov chaw uas hydrogen thiab oxygen react. Nws yog tsim los ntawm ntau lub hlwb sib dhos ua ke, thiab cov ntaub ntawv tseem ceeb suav nrog bipolar phaj, membrane electrode, phaj kawg thiab lwm yam.
