A flow battery is a rechargeable fuel cell in which electrolyte containing one or more dissolved electroactive species flows through an electrochemical cell that reversibly converts chemical energy directly to electricity. Additional electrolyte is stored externally, generally in tanks, and is usually pumped through the cell (or cells) of the reactor, although gravity feed systems are also known. Flow batteries can be rapidly "recharged" by replacing the electrolyte liquid (in a similar way to refilling fuel tanks for internal combustion engines) while simultaneously recovering the spent material for re-energization.

Famous quotes containing the word flow:
“Our sense of these things changes and they change,
Not as in metaphor, but in our sense
Of them. So sense exceeds all metaphor.
It exceeds the heavy changes of the light.
It is like a flow of meanings with no speech
And of as many meanings as of men.”
—Wallace Stevens (1879–1955)
