PEM fuel cell membrane for clean deuterium production?

[ab0032]

I was thinking if it is possible to use a fuel cell membrane to produce very clean deuterium from heavy water for a fusor. If you use electrolysis you have to dry the gas, but from a fuel cell you get over 99.99% clean hydrogen through the proton exchange membrane. Or am I mistaken, does water seep through the membrane too?

Such a membrane can be bought cheaply on ebay, for example from some toy renewable energy construction set or separately.

Now I am wondering, can I use such a membrane to transport deuterium instead of protons too? Any comments or remarks? What do the experts and scientists say, I am very curious.

Here is another link on PEM electrolysis claiming 99.999% gas purity.

And here is someone who has already done it, but not much information otherwise... http://www.radiantmatter.com/content/ne ... g-pem-cell

Hi Alexander.

Good idea, PEM fuel cells for D2 generation. You must have had your back turned when
a very detailed project description was posted on fusor.net a few weeks ago

Thanks for presenting some other links.
Why not start with one of the above, and replicate or improve the design?
