Le generator ye-membrane enothisa umoya-mpilo ihlanganisa ubuchwepheshe obuthuthukisiwe bokuhlukanisa amangqamuzana. Isebenzisa ulwelwesi oluklanywe ngokunembile, isebenzisa ukuhlukahluka kwemvelo kumazinga okungena phakathi kwama-molecule omoya ahlukene. Umehluko olawulwayo wengcindezi ushayela ama-molecule e-oksijini ukuthi adlule ngokukhethayo kulwelwesi, enze umoya onothile onomoya-mpilo ohlangothini olulodwa. Le divayisi emisha igxilisa umoya-mpilo ovela emoyeni ozungezile isebenzisa izinqubo zomzimba kuphela.
