Taw Qhia Rau 5 Hom Roj Roj

Proton Exchange Membrane Roj Cell siv cov khoom siv hluav taws xob hloov pauv raws li cov electrolyte. Nyob rau hauv hom roj cell no, cov roj hydrogen yog pub los ntawm cov anode thaum cov pa oxygen nkag mus rau cathode, nrog rau cov proton pauv membrane ua cov electrolyte ntawm lawv. Thaum lub sij hawm electrochemical cov tshuaj tiv thaiv, hydrogen gas ntawm lub anode yog phua rau hauv protons thiab electrons. Thaum cov protons dhau los ntawm kev sib pauv ntawm cov khoom siv hluav taws xob, cov hluav taws xob ntws los ntawm ib qho hluav taws xob sab nraud, tsim hluav taws xob hluav taws xob. Nyob rau hauv cathode, oxygen ua ke nrog protons thiab electrons, ua dej vapor raws li ib tug byproduct. PEMFCs muab cov txiaj ntsig zoo xws li lub zog ceev ceev, lub sijhawm pib sai, thiab kev hloov pauv tau zoo, ua rau lawv siv dav hauv tsheb thauj mus los xws li tsheb thiab tsheb thauj khoom.

Alkaline Roj Cell siv cov tshuaj potassium hydroxide ua cov electrolyte. Hauv AFCs, hydrogen gas yog decomposed rau hauv hydrogen ions thiab electrons ntawm lub anode. Hydrogen ions hla cov tshuaj potassium hydroxide, thaum cov hluav taws xob ntws los ntawm ib qho hluav taws xob sab nraud, tsim hluav taws xob hluav taws xob. Ntawm lub cathode, cov pa oxygen ua ke nrog hydrogen ions thiab electrons, ua rau dej ua cov khoom lag luam. AFCs nthuav tawm kev hloov pauv kev ua tau zoo thiab ua haujlwm ntev, tab sis vim yog cov tshuaj corrosiveness ntawm cov tshuaj potassium hydroxide, lawv pom cov ntawv thov dav dav hauv thaj chaw tshwj xeeb xws li aerospace thiab kev tiv thaiv.

Phosphoric Acid Roj Cell siv phosphoric acid ua cov electrolyte. Hauv PAFCs, cov pa roj hydrogen tau faib ua protons thiab electrons ntawm lub anode. Protons migrate los ntawm phosphoric acid electrolyte, thaum electrons ntws los ntawm sab nraud Circuit Court, tsim hluav taws xob hluav taws xob. Nyob rau hauv cathode, oxygen ua ke nrog protons thiab electrons, ua dej raws li ib tug byproduct. PAFCs muab cov kev hloov pauv tau zoo thiab kev ruaj ntseg, feem ntau siv rau hauv cov tshuab hluav taws xob thiab cov tshuab cogeneration.

Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob siv cov khoom siv oxide zoo li cov electrolyte. Nyob rau hauv ib qho SOFC, hydrogen gas yog decomposed rau hauv protons thiab electrons ntawm lub anode. Protons migrate los ntawm cov khoom oxide electrolyte, thaum electrons ntws los ntawm sab nraud Circuit Court, tsim hluav taws xob hluav taws xob. Nyob rau hauv cathode, oxygen undergoes oxidation raws li nws ua ke nrog protons thiab electrons, tsim oxygen ions. Cov pa oxygen ions dhau los ntawm cov khoom oxide electrolyte rov qab mus rau lub anode, qhov chaw uas lawv hnov ​​​​mob nrog hydrogen gas, ua dej vapor raws li cov khoom lag luam. SOFCs muab cov txiaj ntsig zoo xws li kev hloov pauv kev ua haujlwm siab, kev hloov pauv roj, thiab kev ua neej ntev, ua rau lawv feem ntau siv hauv cov khoom siv hluav taws xob thiab cov txheej txheem cogeneration.

Lub Molten Carbonate Fuel Cell (MCFC) kuj yog cov roj kub kub uas ua haujlwm molten carbonate ua cov electrolyte. Hauv MCFC, cov roj roj feem ntau muaj kev sib xyaw ntawm hydrogen thiab carbon dioxide. Cov pa roj no yog decomposed rau hauv carbonate ions thiab electrons ntawm thaj tsam anode. Carbonate ions tuaj yeem txav mus los ntawm molten carbonate electrolyte ntawm qhov kub thiab txias, ntawm thaj chaw cathode cov tshuaj tiv thaiv, ua ke nrog oxygen los tsim dej, carbon dioxide, thiab electrons. Cov electrons ntws los ntawm ib qho hluav taws xob sab nraud, tsim hluav taws xob. Kev khiav hauj lwm kub ntawm MCFCs feem ntau yog li ntawm 600 txog 700 degrees Celsius.
