Bromide in chlorate cell?
I recently constructed a sodium bromate cell and it went much better than I thought it would (video).
I next want to try a sodium chlorate cell, but it seems one of the problems a chlorate cell has that a bromate cell doesn’t is the release of
chlorine.
Would adding a small amount of bromide help prevent this? My idea is that any chlorine produced would immediately react with bromide to form bromine
which would stay in solution. The bromine would react with sodium hydroxide to re-form bromide.
Would this work, or would the bromide all convert to bromate and be useless?

Let's see. The chlorine released reacts with bromide to make bromine. Bromine reacts with sodium hydroxide to form bromide and hypobromite.
Hypobromite disproportionates into bromide and bromate. You have a bromide-bromine cycle that converts eventually all bromide to bromate.
What happens when chlorine reacts with bromate?

That is my main question. My best guess is chloride, bromine, and oxygen, with possibly some chlorate.
