Positive or Negative Anode/Cathode in Electrolytic/Galvanic Cell
$begingroup$ @user2612743 In an electrolytic cell you are the person that determines which electrode is positive and which is negative via the external potential. And this external potential doesn''t get altered in the course of the reaction because the "sucked in" electrons are transported away by the voltage source.
