Roj cell yog ib qho khoom siv hluav taws xob hluav taws xob uas txuas ntxiv hloov cov tshuaj hluav taws xob hauv cov roj mus rau hauv hluav taws xob hluav taws xob los ntawm tus neeg sawv cev oxidizing.
Nws muaj cov yam ntxwv hauv qab no:
- roj teeb efficiency siab, vim hais tias nws tsis txwv los ntawm lub voj voog Carnot, nws cov roj teeb efficiency yog 2 mus rau 3 zaug siab dua li ntawm cov pob txha combustion, thiab 10 npaug ntawm lithium roj teeb;
- Cov tshuaj tiv thaiv yog ruaj khov thiab tsis muaj kuab paug, thiab cov khoom tsim tawm yuav tsis ua rau huab cua paug;
- Qhov kev nyab xeeb tseem ceeb yog qhov siab, thiab hydrogen muaj cov yam ntxwv zoo, yog li cov pa xau nrawm nrawm thaum muaj xwm txheej, thiab nws nyuaj rau ncav cuag qhov tawg concentration;
- Daim ntawv thov teb yog dav, thiab qhov chaw ntawm hydrogen yog nplua nuj thiab ntau yam.
Raws li qhov sib txawv ntawm kev khiav hauj lwm kub ntawm lub roj teeb, cov roj hlwb tau muab faib ua proton exchange membrane roj hlwb (PEMFC), alkaline roj hlwb (AFC), phosphate roj hlwb (PAFC), molten carbonate roj hlwb (MCFC), thiab cov khoom oxide roj. Cell (SOFC). Cov yam ntxwv ntawm kev khiav hauj lwm ntawm ntau yam roj teeb muaj nyob rau hauv cov lus hauv qab no.
Table: Kev khiav hauj lwm yam ntxwv ntawm ntau yam roj teeb
| Roj cell | PEMFC | AFC | PAFC | MCFC | SOFC |
| Electrolyte | Nafion | KOH | H3PO4 | LiPO4 | ZrO2 |
| Ua haujlwm kub / degree | 60~80 | 50~250 | 200 | 650 | 600~1000 |
| Catalyst | Platinum | Platinum | Platinum | Nickel | Perovskite |
| Roj compatibility | H2, CH3OH | H2 | H2 | CO, hydrocarbon | CO, hydrocarbon |
| Lub zog ceev / (W / cm²) | 1~2 | 0.5 | 0.1 | 0.2 | 0.3 |
Ntawm cov roj hlwb saum toj no, AFC tau tsim qhov ceev tshaj plaws thiab tau siv nyob rau hauv lub tshav dav hlau fais fab roj teeb. MCFC tau ua tiav theem kev sim ua lag luam; SOFC pib lig, tab sis nws yog qhov kev vam meej tshaj plaws hauv kev tsim hluav taws xob. Txoj kev loj hlob ntawm PEMFC tau kuj paub tab, tam sim no siv los ua lub tsheb fais fab mov thiab cov khoom siv hluav taws xob me me, nrog rau cov txiaj ntsig hauv qab no: kev siv hluav taws xob hloov hluav taws xob siab, mus txog 40% ~ 50%; Proton exchange membrane (PEM) yog ib qho khoom siv electrolyte membrane, uas zoo zam qhov teeb meem ntawm electrolyte corrosion hauv lwm cov roj hlwb. Piv nrog ib txwm muaj zog ib puag ncig zoo, cov khoom tsuas yog dej; Cov qauv yooj yim, yooj yim rau kev ua tiav modularization, roj teeb sib dhos thiab kev saib xyuas yooj yim dua; Lub sijhawm pib txias yog luv luv, thiab cov khoom siv roj xav tau los ntawm hydrogen roj hlwb yog dav. Lub roj teeb lub zog tsim hluav taws xob tsis tshua muaj kev cuam tshuam los ntawm kev hloov pauv, uas tsim nyog rau kev tswj hwm lub zog hluav taws xob. Tab sis tib lub sijhawm, PEMFC tseem ntsib ntau yam teeb meem hauv kev txhim kho yav tom ntej: tus nqi ntawm PEM daim nyias nyias yog siab, thiab kev thov ntau dua; Nws yog rhiab heev rau CO thiab nquag mus rau catalyst lom. High catalyst nqi; Lub neej luv luv, kev ua haujlwm nrawm nrawm thaum siv.
