A positive electrode. In electrolysis anions are attracted to the anode. In an electronic vacuum tube it attracts electrons from the cathode, and it is therefore from the anode that electrons flow out of the device. In these instances the anode is made positive by external means; however in a voltaic cell the anode is the electrode that spontaneously becomes positive and therefore attracts electrons to it from the external circuit.

Chemical Engineering
A positive electrode in an electrolytic cell. In the process of electrolysis in which electricity is passed through an electrolyte, the electrode attracts electrons from an external circuit. Comparecathode.
Electronics and Electrical Engineering
The positive electrode of an electrolytic cell, discharge tube, valve, or solid-state rectifier; the electrode by which electrons leave (and conventional current enters) a system. Comparecathode.
