Foaming Electrolyte

Postby SeaMonkey » Sat Jun 21, 2008 11:49 pm

The usual cause for "foaming electrolyte" is that it has absorbed sufficient Carbon Dioxide from exposure to open air that a significant amount of Sodium or Potassium Carbonate has formed.

Sodium or Potassium Carbonate in solution are very much like soapy water and will support rather large bubbles.

Just drain your electrolyte and refresh it with a new mix.

Avoid exposing your electrolyte mix to the open air for more than a few minutes at most.

Rampage 263,

It is possible that the "friction tape" adhesive you've used to wrap your plate assembly with is contaminating the electrolyte solution and may account for your "foaming."

You may have to find another material which will stand up to the electrolyte solution.

I have opened the cell up many times to change plate stacks. Have two I am testing. It is the same solution that I used to condition the cells and have read it should be changed. Thanks SeaMonkey I had not realized the chemical changes that take place with air.
