Abstract. Nanocarbon particles (Ugleron« and Astralens«) used of the first for metal porous cathode (MPC) production. Although it can be assumed that its implementation in the MPC matrix can change the mechanism and rate of occurrence of three-phase reactions of formation of active elements and oxygen and, thereby, can improve its emission properties. Models with the use of Ugleron« and Astralens« in a sponge and emission substance are manufactured. Layout using Ugleron« in the emission substance is tested for durability and currently has an operating time of 40,000 hours. A model with the use of Astralens« and Ugleron« in a sponge and emission substance, respectively, is tested for maximum current density. To date it shows results comparable to the standard cathode. But there is a suggestion that cathodes with Astralens« and Ugleron« have an evaporation rate of the active substance lower, longer durability is predicted than for the standard cathode at the same emissivity.

Key words: metal porous cathode, nanocarbon particles, emission, durability.
