You can remember this by recalling that current flows from anode to cathode in an ordinary diode; well, that is, if you use the trick of assuming that current is hole flow, rather than electron flow, a useful and common convention.
An anode is an electrode at which current leaves the cell and oxidation takes place... A cathode is described as a negative electrode. Current enters the cell at the cathode and reduction takes place. Electrons are repelled from the cathode.n example is the production of sodium metal from molten salt, or sodium chloride. When the current flows, positively charged sodium ions are attracted to the negative electrode, or cathode, where they gain electrons, forming sodium metal.
