Anode

[technoguy]

An anode (from the Greek άνοδος = 'going up') is the electrode in a device that electrons flow out of to return to the circuit. Literally, the path through which the electrons ascend out of an electrolyte solution. The other charged electrode in the same cell or device is the cathode

[vipl]

Inside chemical cells, there are two currents: negative ions (anions) flowing from cathode to anode, and positive ions (cations) flowing from anode to cathode, resulting in a net movement of electrons from cathode to anode. Inside solid state or transistor type cells the flow of electrons is also from cathode to anode within the cell.
