Continuous hydrogen generation apparatus and hydrogen generation method

The purpose of the present invention is to provide: a hydrogen generation apparatus which can be driven continuously for a long time; and others. The hydrogen generation apparatus (10) is equipped with: a first pipe (661) through which water can be supplied to the inside of a reaction vessel (21); a second pipe (662) through which a liquid suspension containing a powder of a hydrogen-generating material dispersed in water can be supplied to the inside of the reaction vessel (21); a third pipe (663) which is connected to an upper part of the reaction vessel (21) and through which hydrogen is allowed to flow out, wherein the hydrogen is generated by the reaction of water supplied through the first pipe (661) and stored in the reaction vessel (21) with the hydrogen-generating material contained in the liquid suspension supplied through the second pipe (662); and a drainage pipe (666) which is connected to a lower part of the reaction vessel (21) and through which a reactive product is allowed to flow out, wherei
