The present invention relates to the technical field of hydrogen fuel power generation, specifically a hydrogen fuel high-speed rotating magnetohydrodynamic power generation device. The device comprises a shaft portion, a cover plate portion, a thin plate portion and a combustion propelling portion. The device craftily utilizes hydrogen electrochemical reaction and direct combustion of unionized hydrogen to complete the hydrogen catalytic ionization reaction while providing jet thrust for rotation. Advantages are that it is more efficient than hydrogen fuel cells, has high power density, which is suitable for high-power and high-energy power needs, utilizes no key special components and does not require auxiliary systems such as heat dissipation, breaking limitations of proton exchange membrane on hydrogen fuel cells and low efficiency of a Carnot cycle on hydrogen internal combustion engines.
