The high power space power system is in urgent demand for the next generation aerospace missions. This paper presents the ground-based experiment of the high temperature inert gas Faraday type MHD generator first conducted in China, with arc heater as the heating source, argon the working gas, and cesium injected to improve the conductivity of the working gas. The faraday type MHD generation is successfully carried out, with the maximum output power reaching 194 W under 1 T magnetic field strength and the power density being 866 kW/m3. Three-dimensional numerical simulation is conducted under the experiment conditions, showing that the MHD generator output character is largely affected by the seed injection effect and working gas velocity. To avoid these problems, the generator processing technology needs to be improved to reduce the voltage drop, and the nozzle needs redesign.
