Eh, Paul, you caught me outta me depth. I know it sounds "mysterious",
but that's the gist of what I understand. Remember, I only deal with
electrons once their freed from their slavemasters, them nasty
despicable (read that with the requisite Daffy Duck slur) chemical
atoms. Methinks we both need to read that SAE article FrankP mentioned
previously. Usually when the electrochem guys talk 'down' to the mech &
elec types, they couch things in terms we can understand. Course, if
you're a physics type, hey no problemo I s'pose.

Anway, yes, I think your guestimate description above is as good as I
understand the phenom; I remember a Japanese article I saw once, the
only thing in english was the abstract, and that's how they described
it: a solid electrolytic pump that moves oxygen ions around under
electrical command. Swell gizmo, eh?

P.S. To any electrochem guys that read my words and wince, get off yer
duff and eXplain it to the rest of us lower lifeforms; otherwise, quit
yer complainin.
