| The third electrode may be biased at the potential of the anode through a ballast resistor, and be located near the cathode. |
| Current can only flow from the anode to the cathode, but not the other direction. |
| Meanwhile, copper atoms in the positive anode give up electrons and dissolve into the electrolyte solution as copper ions. |
| The fuel cell also needs moisture in the electrolyte as well as water at the anode to control the supply of methanol. |
| However, the sodium channel inactivation gates are open in the hyperpolarized virtual anode region, causing the tissue to be excitable. |
| The avalanching electrons move toward the anode, causing the applied voltage to collapse in picoseconds. |
