Solid hydrogen fuel, manufacturing method and use method thereof

The invention relates to a solid hydrogen fuel which is a solid compressed block. In the manufacturing process of the solid hydrogen fuel, at least one hydride powder and at least one hydrogen-generating catalyst powder are uniformly mixed, and then the mixed powder is taken out and compressed into blocks; when the solid hydrogen fuel is used, the solid hydrogen fuel is mixed with water to generate hydrogen, wherein the hydride powder and the water are subject to a hydrogen-generating reaction, and the hydrogen-generating catalyst powder is used for catalyzing the hydrogen-generating reaction to generate hydrogen. The solid hydride has higher hydrogen generation, and can release hydrogen effectively and completely.
