Reduce chlorine gas

I have a simple electrolysis setup which uses aqueous sodium chloride as electrolyte. The problem is that, the setup makes tons of chlorine gas along with hydrogen (I only want hydrogen). I didn't even realize it until I recognized that the odor smells like that of ozone. I am using a power supply of 24V @ 6A. Since, it's a pain to buy a new power supply, changing the supply isn't an option. Also, I have experimented with other electrolytes like aqueous sodium bicarbonate but they are far slower than the brine solution. So, the only other option is to consume the chlorine gas. I am not sure what to use here. I don't have a lot of reducing agents on hand. Any ideas?

If anyone is curious as to how I know what ozone smells like, I have experimented with lots of high voltage. It makes your throat feel dry. Chlorine does that too.. –  AvZ Aug 24 at 13:15
plainly keep your cell at temperature well above 50+C. In such conditions sodium chloride is oxidized to chlorate and later perchlorate. Another option is to try and use something else, like sodium hydroxide or magnesium sulfate. –  permeakra Aug 24 at 13:28
