Wiki has a pretty good article on electron affinity:

Here is the thought (I have not checked to see if this
is a "re-invention" of someone else's idea) - take two
electrodes and a working medium, and hydrogen is the
only working medium that fits into this concept very
well (73 kj/mol)...
- such that one electrode has a much lower electron
affinity than does the H2 (zinc works well ~0) and the
other has a much higher (gold plated copper works here
~223).
The donor electrode might be a slightly conductive plastic, or other
triboelectric donor material, which would thus also directly provide
the capacitive linkage. The trickle current though it would have to
be enough to recover for the next pulse. The electron donor -
transporter combination is still important if tribolelectric effects
are used to achieve the donation because that is in fact an electron
affinity effect.

Candidate electron transporter molecules might come substances from
the list of "accumulator oils" provided in the above article:
Accumulator oils
=============================
Natural gasolines
Kerosenes
White spirits
Motor and aviation gasolines
Jet fuels
Naphthas
Heating oils
Clean diesel oils
Lubricating oils
CO2 might be a candidate transporter molecule, and a CO2-Steam mix
might be effective, with one being more effective acceptor, the other
a more effective donor, with gas born electron exchanges involved in
addition.
