In a galvanic cell, the source of the electrons is the anode, and the source of the protons is the cathode.

Explanation:

In a galvanic cell, electrons will move in to the anode. Since electrons carry a negative charge, then the anode is negatively charged.

Same thing with the cathode.

It's because the protons are attracted to the cathode, so it's mainly positive, and therefore is positively charged.
