yes, since two generators would be putting out rectified AC waveforms ( like upside down U's UUUUUUUU ), the charged cap will try to backfeed the generator when it is at the low point of its AC waveform

the diodes would let the generator pump the cap up to 12 or 18 volts, but the cap would not be able to send current back into the generator as the brushes are switching from one set of windings to the next on the commutator.

to find diodes, try the search function on www.digikey.com

like this 30A 50V rated power diode for example: http://www.irf.com/product-info/data...0ctq050pbf.pdf
