An electrode structure for use in an electric discharge device includes a fluid-permeable discharge chamber; a flow of gas seeded with actively emissive elements is delivered to the interior surface of said discharge chamber for a distributed electric discharge to be maintained thereat. The discharge chamber is fitted with an opening providing for a discharge channel outlet. Service life of the proposed electrode structure reaches several thousands of hours, which is possible due to erosion inhibition at the discharge surface. Simplicity of design, reasonable weight and dimensions of the electrode structure renders it suitable for use as an electrode in plasmatrons employed in chemical industry and metallurgy, as well as an electrode for electric arc melting furnaces. The electrode structure can also be used as a welding electrode, and as an electrode for MHD generators and other electric discharge devices with electric arc heating process being used therein.
