Very interesting, I am attempting to build a Brown's gas generator (electrolysis generator) but am having huge problem with the electrolyte turning red, this seems to be happing because of the iron on the 316 stainless steel plate surface, I did a couple of types of passivation but was not successful in stopping the reddish colouring appearing in the electrolyte, I'm wondering would your electropolishing method work? Am I right in understanding that the two solutions in the beaker need to be heated and if so what temperature? Great video.

316 should be fine for an oxyhydrogen generator. The red is usually iron from the plates corroding. Can't remember if due to excess voltage or current, but I am fairly certain it was current. There are recommendations to limit either voktage or current to a certain amount per square cm of each electrode. Back when I messed with it we just used those square 316 sheets, I think like 8"x8", or 6"x6" plates separated maybe 1/8 or so apart. But voltage was pretty low, 12v. Electrolyte was KOH or NaOH. Some people used both. Tl;dr 316 is fine, but your volts/amps/electrolyte or something else in your setup is not right and it's corroding your plates.

Does it make toxic chromium gassed or compounds?

Hi - no real problem with chromium toxicity and no toxic gas is evolved- the main hazard is handling concentrated sulphuric acid during the mixing process. hope that was useful reply and thanks for your question - we will make more in-depth videos soon
