NOVELTY - A hydrogen-producing apparatus has a solid hydrogen-producing agent which generates hydrogen by reaction with reaction liquid, generating agent accommodating portion (1) which accommodates solid hydrogen-producing agent, a bottom cylindrical reaction liquid storage portion (2), a reaction liquid container (3), a reaction liquid supply portion which supplies reaction liquid to generating agent accommodating portion from reaction liquid container, and hydrogen supply path which supplies hydrogen gas generated in generating agent accommodating portion.    USE - Apparatus is used for producing hydrogen for fuel cell.    ADVANTAGE - The hydrogen-producing apparatus has simple and compact structure.    DETAILED DESCRIPTION - A hydrogen-producing apparatus has a solid hydrogen-producing agent which generates hydrogen by reaction with reaction liquid, generating agent accommodating portion which accommodates solid hydrogen-producing agent, a bottom cylindrical reaction liquid storage portion which stores the reaction liquid, before reaction start, a reaction liquid container which is provided outside the generating agent accommodating portion, and space between generating agent accommodating portions is filled with reaction liquid, a reaction liquid supply portion which supplies reaction liquid to generating agent accommodating portion from reaction liquid container, and hydrogen supply path which supplies hydrogen gas generated in the generating agent accommodating portion. The reaction liquid is filled in the space with insertion of reaction liquid container through reaction liquid pouring path formed in the vessel bottom surface of reaction liquid container from the opening end of reaction liquid storage portion. The solid hydrogen-producing agent and reaction liquid are reacted in hydrogen-producing apparatus to generate hydrogen.
