We record voltage and current, so we have IONS into our cells.
So we have ionization of the gas.
It is unlikely that it is energetic particles that produce this ionization, otherwise it would require considerable radioactivity. (Like pure polonium layer on the glass)
Palladium cathodes can release hydrogen atoms. We demonstrated this with John Giles by making a special paper that changes color in the presence of atomic hydrogen / After loading with deuterium, a palladium cathode leaves its mark on the paper.

But these atomic hydrogen atoms, while very reactive, are not charged. And this is a chemical reaction, it does not last long.
But Frank Gordon observes voltage and current for several weeks.
Subject to verification, it is possible that we have a photochemical (or "nucleochemical") reaction ON THE SURFACE of the palladium: the energy of nuclear origin released in the palladium undergoes a down-conversion, and on contact with palladium we would have the following reaction:
H ° (adsorbed) à H+ (gaseous) + e-
And : H2 (adsorbed) à H2+ (gaseous) + e-
Palladium therefore takes a negative charge, and the metal electrode located in front therefore takes a positive charge when the positive H+ and H2+ ions (and the H3+ ions) are neutralized on the opposite metal electrode with the reverse reaction.
This reaction would provide a convenient way to convert the energy released by LENRs into electricity.
