"A voltaic cell functions only when the electrical circuit is complete. In the external circuit the current is carried by the fl ow of electrons through a metal wire. Explain how the current is carried through the cell itself."

Can someone please explain this to me? The solution manual says a negatively charged electrolyte flows from the cathode to the anode, but why is this? Shouldn't it flow from anode to cathode if it is negatively charged?

I think it flows from cathode to anode because if it's a negatively charged electrolyte, that implies that the reaction is non-spontaneous due to a negative voltage. Because spontaneous reactions are spontaneous when the electrolyte flows from anode to cathode, non-spontaneous would just be the reverse.
