cath·ode

(kăth′ōd′)
1. The negative electrode in an electrolytic cell, toward which positively charged particles are attracted. The cathode has a negative charge because it is connected to the negatively charged end of an external power supply.
2. The positive electrode in a voltaic cell, such as a battery, toward which negatively charged particles are attracted. The cathode gets its positive charge from the chemical reaction that happens inside the battery, not from an external source. Compare anode.

cathode

1. The electrode carrying the negative charge in a solution undergoing electrolysis.
2. A negative electrode.

Figure 3 shows electronic pulses curve from pulsed field emission of CNT cathodes irradiated by laser pulses, on the same working condition of laser pulses except different applied voltage of 100 V, 400 V, 700 V, and 1000 V, respectively, contrasting to the insert of emission current density of cathodes without laser illumination by field emission without laser illumination.
The best electrochemical performances of GDE1 and GDE2 are achieved when working as anodes, while poor results are obtained if they are used as cathodes. Assembly 1 is always superior to Assembly 2 in any operating condition.
