You can remember this by recalling that current flows from anode to cathode in an ordinary diode; well, that is, if you use the trick of assuming that current is hole flow, rather than electron flow, a useful and common convention.
The copper electrode is therefore the cathode. Both cathode and anode are types of electrodes. Actually electrodes are dipped in chemical solution (electrolyte). One electrode which is given positive charge is called anode while electrode with negative charge is called cathode.
