Hypochlorite Generator
Need to do a patent search on this if I ever have time but sure looks sweet!

NaOCl
I'm very sure this produces NaOCl, not free chlorine. Granted, NaOCl is more useful in my opinion, but this might not be what you think it is. I
don't know what you are looking for.
I looked into these and other products about two years ago for home production of commercial quantities of NaOCl, which is perhaps the single most
useful chemical in existence to be able to manufacture for free.

Also
It would be much cheaper to build such a device yourself, than to buy theirs. Such a device is very simple in construction, and you could purchase
their electrodes as replacements from them. All you need to do is mimick the cell chamber dimensions and supplied power specifications. Using their
electrodes eliminates the need to calculate amperage concentration on the electrode and determine adequte electrode dimensions.
Their device is quite pricey for something I could produce for under $40 (not including electrodes).
If you want to scale things up, you will know the exact electrode dimensions and materials. You could buy larger electrodes from a lab supplier and
then build a new power supply that supplied enough current at the same voltage potential so as to have equal amperage / unit surface area on the
larger electrode.
Fun stuff.

So, this is an old topic but its relavant to my current project and I in looking for some wisdom. From what I can see the chlorate cell I'm building
does the same thing as a hypochlorite generator... is the difference in output just a factor of the operating temperature? Google tells me that
hypochlorite generators work at under 40 degrees and chlorate cells work at 50-70 but I never see it in the same article. Will my cell only produce
hypochlorite if the current doesn't heat it enough? (I'm sure it will though!)

Hypochlorite
Temperature definitely affects the products formed. At cold temperatures chlorine gas
dissolved into solutions of hydroxides forms the hypochlorites. At higher temperatures the
chlorates are formed. Additionally, at higher temperatures, hypochlorites oxidize to chlorates.
This is the thermal decomposition mentioned on Wouter's website and other pyrotechnic
sites. An example:
3NaOCl --> NaClO3 + 2NaCl

So it the same process turns a chloride into a hypochlorite, chlorate, and perchlorate why don't I hear about chlorite cells? Is that one skipped for
some reason?

Chlorite is less stable than chlorate, chlorate usually has to be reduced for form chlorite IIRC.
