To summarise my experience with the technology so far here it is: The cell walls need to be made of ABS as polypropylene is gas permeable to carbon dioxide. The electrodes need to be assembled with nickel plated metals to stop corrosion. The rubber gaskets deteriorate and leak gas so need to be...

There are 2 orings per terminal. One is inside the cell against a smooth surface with a shoulder, the other is threaded and accessable from the top. There is a spacer plate inside between the 2. They both get squashed by a single nut from the top. The design of these cells are not brilliant as...

They are from Seawill in china. They are a few years old and don't really do much other than power a ventilation fan to the box they are in and charge off solar panels. This is just a hobby I've picked up for testing renewable stuff...

Hello, thanks for the reply! Damn... I noticed that there was this white powder forming around the top of the cells and couldn't work out where it was coming from. The stuff seems to get everywhere and has corroded the bottom of my metal box I've stored them in. I'm guessing the o-rings must be...

Hello, I've been experimenting with some NiFe cells from China on a solar powered shed and I have a questions about the electrolyte degradation. Is it possible to stop the carbon build up by using pressurised recombiner vent caps like this one...
