Provided is a hydrogen generator which is capable of reducing a size of an entire apparatus and reducing a running cost by utilizing heat of a heat exchanger (1) for hydrogen reforming in a reformer (2), and which can particularly preferably be used in a facility such as a hospital, a restaurant, or a hotel utilizing both steam and electricity, and a fuel cell system using the hydrogen generator. The hydrogen generator includes the reformer (2) for generating hydrogen H 2 from a fuel gas G and steam H 2 O incorporated in a fuel gas passage (12) of the heat exchanger (1) provided with a water pipe (13). The hydrogen generator utilizes a part of heat of the heat exchanger (1) for hydrogen reforming performed in the reformer (2). The hydrogen generator includes the reformer (2), a converter (3) for generating hydrogen from carbon monoxide generated in the reformer and steam, and a CO remover (4) for removing a carbon monoxide gas generated in the converter (3) . The reformer (2), the converter (3), and the CO remover (4) are arranged in the flue gas passage (12) of the heat exchanger (1). |
