    Not sure what you mean by "a cathode is always a cathode". If you are refering to the fact that a Cathode can be both +ve and -ve (as well as an anode) then yes he has explained that fact. That rather then anode and cathode being specified by charge that it is specified due to which is oxidized...

    My chem teacher is having trouble explaining the a particular happening in a fuel cell to the class. In a galvanic cell +ve ions move towards the +ve electrode and -ve to the -ve. In electrolytic cells the +ve ions move towards the -ve electrode and -ve to the +ve. He says that the reason why it...
