Non-asbestos Porous Diaphragm for Water Electrolyser

Non-asbestos Porous Diaphragm for Water Electrolyser

Non-asbestos Porous Diaphragm for Water Electrolyser

(OP)
Hi everyone!

I am currently looking for specific data for a product called Ryton felt which comes in various densities, 10 and more ounces per square yard, according to what I read.

This material is widely used for cleaning flue gases and for filtering various types of effluents. It is commonly found in bag houses.

I read on the Internet that Ryton is used for making porous diaphragm between anodes and cathodes in water electrolyser. "A major limitation is the operating temperatures of organic materials, generally less than 120 degrees Celsius, although materials such as Ryton and PTFE are stable at temps up to 160 C." http://www.ahanw.org/forum/topic.asp?TOPIC_ID=330

I would like to know more, such as how is the Ryton fashioned for this application. Is it a finely perforated sheet, a tightly woven fabric, a felt, a knit, etc?

What would be the density, the porosity, the fiber size, etc, to at once provide for efficient ion migration(be permeable to the electrolyte) and for efficient gas bubble confinement (be impermeable to gas)?

I need to know these specific details in relation to making low-tech electrolyser on my own, with your help, I hope.

Thanks.
