https://en.wikipedia.org/wiki/Nonthermal_plasma

Non-thermal plasma, or non-equilibrium plasma is simply a plasma where the electrons are a much higher temperature than the ions.

Normally the research on plasma electrochemistry focuses on using non-thermal (or thermal) plasma as a catalyst, but I was wondering about the possibility of using the plasma itself as the ion exchange membrane/electrolyte in fuel cells.

For the life of me, I can't find a single article attempting on using it in such manner. At best, the papers use it for electrolysis of water, but never as a fuel cell.

I found flame assisted fuel cells and direct flame fuel cells, but nothing about plasma fuel cells.
