Abstract:
An apparatus for producing hydrogen by a steam reforming reaction, on a catalyst, of a hydrocarbon or an oxygen-containing hydrocarbon as a raw material, comprising:a hydrogen separation type reformer which has a means for heating the catalyst and which has a hydrogen separation membrane built into a layer of the catalyst for selectively separating hydrogen; a cooling means for cooling high temperature high purity hydrogen obtained from the reformer; and hydrogen charge/discharge means disposed downstream from the cooling means and composed of a hydrogen storage material, wherein: the cooling means for cooling the high temperature high purity hydrogen comprises an indirect heat exchanger, wherein: the hydrogen charge/discharge means composed of the hydrogen storage material comprises at least two members of a hydrogen storing alloy incorporating a heating/cooling means, and wherein: a fluid for cooling the high temperature high purity hydrogen via the indirect heat exchanger is cooling water; and hot water heated by heat exchange performed by the heat exchanger is used for heating of a hydrogen delivery means in the hydrogen charge/discharge means composed of the hydrogen storage material.
