NOVELTY - Hydrogen generator apparatus comprises first apparatus assembly (1) including first container (3) for holding reactant for generating hydrogen, reaction chamber (5), second container (6) for collecting reaction waste product, and conveying tube (9) for transmitting prepared hydrogen; and second apparatus assembly (2) which can be connected with first apparatus assembly via drive element (23, 24, 25) of pump apparatus. The first container is connected with reaction chamber via work chamber of pump apparatus. The pump apparatus is peristaltic pump apparatus (21).    USE - Hydrogen generator apparatus.    DETAILED DESCRIPTION - The first apparatus assembly is disposable assembly. The work chamber of peristaltic pump apparatus is connected with first container and inside of hose (22) of reaction chamber. The pump drive element includes at least one rod that rotates around circular center of arc, such that when assembly is connected, rod is carried with roller to extrude hose. It further includes motor for revolving rod so that extrusion position can be shifted on arc. The rod includes cylinder and is provided at periphery of cylinder on direction parallel to axis of cylinder. The second apparatus assembly includes inserted module which is inserted into arc by first axial shift and second radial shift. The inserted module comprises clamp component composed of spring bolt (29). The first apparatus assembly also includes guide slit (27) for inserting spring bolt. The first and second containers are composed of bags. Gas (8) can be vented through parts of bags but liquid and solid cannot be penetrated. The bag is located in cylinder (7) so that its volume can be changed. Fixing bed catalyst is loaded in reaction chamber. Fuel battery apparatus is connected with second apparatus assembly and communicated with hydrogen conveying tube of first apparatus assembly.
