WSM Posted April 24, 2014 Share Posted April 24, 2014 Just wondering, I'm using the +5v on the power supply for chlorate cell, but should the voltage be the same or higher for perchlorate cell?I really hate the fact that oxidizing.110mb.com is gone, it had so much information. I recall a voltage range somewhere around 6Vdc-7Vdc for perchlorate cells (I may need to correct these numbers later). The information from oxidizing.110mb.com is out there. Maybe someone who's recorded it can send you a copy... WSM Link to comment Share on other sites More sharing options...

taiwanluthiers Posted April 24, 2014 Share Posted April 24, 2014 Does anyone have copies of oxidizing.110mb.com archived and can re-host it? The oocities site is outdated and there's no telling how long it will remain up. Link to comment Share on other sites More sharing options...
pyrojig Posted April 24, 2014 Share Posted April 24, 2014 Thank you for the site copy pyrochili. That is a very good question Taiwanluthiers . I hope somebody will get it back online, as it is a invaluable source of info, that I refer to often. SHeesh ,,,,,, who would let such a gem go to waste. ???

pex Posted April 24, 2014 Share Posted April 24, 2014 Can i use more than one atx supply s? I want to connect a second one to get more ampère. I fillt my cell yesterday. Start with 55 degrees Celsius. This morning hè was 20 degrees. And the whole anode. Was covert in cristalls. My power supply can deliver 25 amp. I have a nother one. Who can deliver 20 amps. Can i just connect the second power supply. To the anode? My cell is 9 liter. And I Dissolve 9 kilo of naclo3. Pex Link to comment Share on other sites More sharing options...
taiwanluthiers Posted April 24, 2014 Share Posted April 24, 2014 Are you making sodium or potassium perchlorate? You shouldn't have crystals of sodium perchlorate because it's more soluble than sodium chlorate. I think connecting 2 power supply should be fine if they both work in tandem... just make sure both are powered up at the same time. Link to comment Share on other sites More sharing options...
pex Posted April 24, 2014 Share Posted April 24, 2014 How do you put them in thandem? Can i just turn them on with 1 power supply conected to electrodes than put the second one to the electrodes while he is running?

And I Dissolve 9 kilo of naclo3.Pex The basics of combining DC power supplies is: for double the voltage, run the outputs in series (positive to negative and out). For double the current, run them in parallel (positive to positive, negative to negative and out). The most important point by my understanding is to match the supplies perfectly or one of the two supplies will "hog the load" and the user risks burning them out, one at a time. I believe matching the supplies involves both their inputs and outputs (voltage AND current) matching as closely to each other as is possible. Especially the outputs, if they're adjustable, should be dialed to match each other for the best results. Also remember, for higher current carrying (the lower voltage part of the power supply), to use larger conductors. The input may be 18 gauge wire, but for a 30A output, it's better to use 10 gauge wire (or two 12 gauge wires in parallel).

WSM Posted April 24, 2014 Share Posted April 24, 2014 Pex, I noticed that your cell is using alligator clips as a connector. There will be losses and waste of power to the electrodes . Heat will be one of these , and any oxidation will reduce the connection even further. If I where to suggest anything , it would be to bolt on your wire via connectors etc.. This will maximize the power delivered . Pex, there's something else I just noticed. The hydrogen vent, in use, should run straight up like a chimney or problems will develop.

pyroChile Posted April 25, 2014 Share Posted April 25, 2014 Hi pyroChile, The article link is one I've seen, and 7Vdc is useful for perchlorate cells. The current delivery depends on the power supply and the configuration of the setup. I'm planning on using 6Vdc with my first experiments. Let us know how it works for you. WSM Hello WSM How is your power supply? =) Link to comment Share on other sites More sharing options...
WSM Posted April 25, 2014 Share Posted April 25, 2014 (edited) Hello WSMHow is your power supply?=) Hi pyroChile, Thanks for asking. I have a few power supplies, but none are a modified computer supply. The one I was thinking of using is a regulated 5Vdc, 30A supply I've used for small chlorate cells. It has a voltage adjust potentiometer and I turn it down to 4.3Vdc for the chlorate cell, but I'll turn it up to as close to 6Vdc as it can get for use in the perchlorate cell. Another option is a larger, rack mount power supply which is rated at 5Vdc and 60A, but I'm afraid it will overpower the LD anode (maybe not, but why take chances?). The voltage adjust on it will go down to 3.75Vdc or up to about 6.5Vdc (if I remember correctly). I also have a variable power supply which runs on 240Vac (the other two run on 120Vac) with an output range of 0-40Vdc and 0-75A, and that one would be very nice for experimenting with new systems, but I need a better place to set it up. Anyway, I need to set up a small experimental perchlorate cell and then decide which power supply to use. It's starting to look like I'll make it happen on the weekend. I'll try to photograph it and post reports here. WSM Edited April 25, 2014 by WSM Link to comment Share on other sites More sharing options...

WSM Posted April 25, 2014 Share Posted April 25, 2014 Ok, You have a pictures of your power supplys?, What kind it is?Thanks for you reply!=) OLD, primarily. I found photos of two of the three: This is the 5Vdc 30A supply. It cost about $20. This is the variable supply (0-40Vdc 0-75A) and I paid about $50 because they couldn't test it (or I'd have to pay more!). I like to add digital panel meters so seeing the voltage or amperage is easier. I hope this helps. WSM Link to comment Share on other sites More sharing options...
