Anode: Where oxidation occurs. We need an iron electrode, where Fe ions are produced, as well as electrons which leave the anode. The iron anode therefore produces a source of electrons.
Cathode: Now the electrons come in here. Because of this, we need an unreactive electrode (Platinum, graphite etc)
(I know this explanation is sloppy, someone might explain better)
