The invention relates to a hydrogen nozzle of a hydrogen fuel engine. The hydrogen nozzle comprises an upper nozzle part, a lower nozzle part spout section and a hydrogen supply pipeline; a hydrogen collecting cavity is formed in the upper nozzle part; the hydrogen supply pipeline of the nozzle is connected to the hydrogen collecting cavity; the hydrogen nozzle is provided with a cooling pipeline and a cooling inlet pipe; the cooling pipeline is mainly located at the lower nozzle part spout section; an inlet of the cooling pipeline is connected to the cooling inlet pipe; an outlet of the cooling pipeline is connected to a cooling outlet pipe or the hydrogen collecting cavity; and the cooling pipeline is a linear or curvilinear combined pipeline adopting a spiral shape, a grid shape, a grille shape or other shapes and adopts an independent circulation mode or a non-independent circulation mode. The hydrogen nozzle has the cooling function, and therefore the temperature of the nozzle can be decreased, the therm
