The invention provides a novel magnetofluid electric generator without seeds. Conducting flow at the temperature ranging from three thousand DEG C to four thousand DEG C works in the magnetofluid electric generator and is gas ionized at high temperature. In order to conduct effective electric generation, on the basis that the conducting performance of the ionized gas cannot meet requirements, seeds, namely metal ions such as potassium and cesium are added; while, when airflow containing the metal ions passes through an electric generating channel in a high-intensity magnetic field at high speed and reaches an electrode, the electrode is corroded. Rapid corrosion of the electrode is the largest problem for the magnetofluid electric generator, and seed recycling problem also exists. Therefore, the novel magnetofluid electric generator without seeds solves seed adding and recycling problems, and avoids inconvenience caused by corrosion of the channel electrode.
