Original text
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.

Revised text
A flow battery is a rechargeable fuel cell in which an electrolyte containing one or more dissolved electroactive species flows through an electrochemical cell that reversibly converts chemical energy directly to electricity (An electroactive species is "A species in solution that can take part in an electrode reaction or that can be adsorbed on the electrode" ). 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.

In other words, a flow battery is just like an electrochemical cell, with the exception that the ionic solution (electrolyte) is not stored in the cell around the electrodes. Rather, the ionic solution is stored outside of the cell, and can be fed into the cell in order to generate electricity. The total amount of electricity that can be generated depends on the size of the storage tanks. One benefit to this design is that the cell can be recharged simply by changing out the tanks.

I thought your changes were great. The rewording of their chem babble was easy to understand and I like how you linked it to the electrochemical cell, the only things I caught were: In your insert for "electroactive species" you have an opening bracket but not a closing one. Also you added the word "the" "...which the electrolyte containing one or more dissolved electroactive species..." I personally think it would be easier to read using "a" but that may just be me.

Hope this helps, and good job.

Changes were very comprehensive. Your further elaboration on the more complex concepts helps to make the information available to a wider audience and it "flows"(pun intended) much better. There are some words from the original that are kept in that are technical, however there may not be any proper substitutes. That is just nitpicking. Great job, KVuong (talk) 18:41, 6 June 2013 (UTC)
