This device has a cathode inside an anode wire cage. Dendrites penetrate the separator between the anode and the cathode causing short circuits. Gas flows through the ion source between the anode and the cathode. Two are a conventional anode and cathode. The high-temperature and carbonate electrolyte lead to corrosion of the anode and cathode. Relatively few hydroniums/hydroxide ions reach the cathode/anode. The concentration polarization occurs in both the anode and cathode. The opposite of an anode is a cathode. Measurement of the concentration changes in the anode and cathode compartments determines the transport numbers. The Ignatron had a cathode, anode and an igniter. This plasma then conducts electricity between the anode and the cathode, closing the circuit. The buffers used at the anode and cathode may be the same or different. A triode has three electrodes&colon; the anode, cathode, and one grid, and so on. This is because the distance between the cathode and anode is relatively small. The tube had a third electrode, an anticathode connected to the anode.
