The TES-200 is an eco-friendly hydrogen fuel cell generator and can be used conveniently outdoors because hydrogen can be self-sufficient. Hydrogen is produced directly in the hydrogen cartridge using hydrogen compounds, catalysts, and water, and the produced hydrogen is stored in a hydrogen buffer, and electricity can be generated by supplying it to a fuel cell. The output may be directly used by the user through the USB port and may be used for power bank charging. The TES-200 can produce 200 Wh, and the power generation time can be adjusted according to the capacity of the hydrogen cartridge.
