New cell not pulling more than 5 amps.

[Clown123]

Hi this is my first post on here so hello everyone ,

I have built my first dry cell it's 8 plates +nnnnnn- setup , plates are 6 inch 5 with gaskets they have 3 holes drilled in the top of each plate for hho to escape and one hole on the bottom for flow into the cell

It has 14 v into the cell but only drawing max of 5-6 amps ?

I have used up all my koh flakes now trying to get it to work via changing mixture but even with 500 g in 1 litre of water still the same ?

After about 30 mins the water was warm not hot but warm is that normal ?

I used a one litre bottle to test the output and it took about 2 mins to do 1/4 litre so not very good at all

The bottom of the feed tank / bubbler combined is about 2 inches above the top of the cell but I did try it a little higher but no change ,

There seems to be a gush of circulation once every few mins in between is just a bubble a second but the bubble is about the size do a 10 p in the pipe

Sorry for long post

Thanks

Lets start with the Power supply. What power supply are you using?

Hi I'm using a 12 v leisure battery with the car running so volts are around 14.5 v

OK the power supply does not sound like it is the problem. It could be the wire size or your connections. Make sure there is not short between your plates and each pair/cell is getting about the same voltage. How thick are you gaskets? Pictures might help. Maximum KOH is 28% by weight.

28% = 389g per Liter of distilled water This is MAXIMUM for KOH

Hi sorry for the delay replying , I have tested again and with the bubbler higher I get better flow and around 6 amps with 200g of koh in 1 litre of water , If I change connections to miss the first plate and the last plate so it's 6 plates it draws about 10 amps and bubbles away quite nice but still only getting around 1/2 per 2 mins ! The gaskets I think are about 2mm but I will have to check , I will also post a pic when I get change

Thanks for your help
