Wiki has a pretty good article on electron affinity: http://en.wikipedia.org/wiki/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).
It just occurred to me that a bunch of cells linked capacitively in series would make a good pulse amplifier. A negative pulse hitting the first cell eliminates the thermal bias required for electrons to be transported cross the cell by the transporter molecules, and the net electron affinity of the transaction adds to the negative voltage applied to the cell acceptor electrode, which then transmits it through a capacitive link to the next cell, thereby avoiding the metal to metal junction bias otherwise required to link the cells conductively. Following the pulse with a brief recovery time gives the cell donor electrode time to reload some molecules with electrons.
