Cathode carries a positive charge.

In a galvanic (voltaic) cell, the anode is considered negative and the cathode is considered positive. This seems reasonable as the anode is the source of electrons and cathode is where the electrons flow. However, in an electrolytic cell, the anode is taken to be positive while the cathode is now negative.

At the cathode, reduction reactions occur and as the reduction reaction requires electrons, the cathode will always have roughly no concentration of electrons on itself. So, it is positively charged.
