Abstract

The disclosed hydrogen generation device (100) is provided with a reformer (4) for generating hydrogen-containing gas by means of a reforming reaction using a raw gas, a raw gas supplier (13) for supplying raw gas to the reformer (4), a methanation unit (6) for decreasing by a methanation reaction the carbon monoxide contained in the hydrogen-containing gas, and a controller which, if the temperature of the methanation unit (6) increases, controls the raw gas supplier (13) to decrease the amount of raw gas supplied to the aforementioned reformer (4) in order to decrease the amount of hydrogen-containing gas generated.

Description

technical field [0001] The present invention relates to a hydrogen generating device and a fuel cell system. Background technique [0002] Currently, a hydrogen gas supply system is not provided as a normal infrastructure. Therefore, in a large amount of equipment requiring hydrogen, such as a fuel cell system developed as a distributed power generation device and promoted for commercialization, a hydrogen generator is often independently installed side by side at the installation site of the equipment. [0003] The hydrogen generation device is equipped with a reformer that generates hydrogen-containing reformed gas through a steam reforming reaction of hydrocarbon-based raw materials such as city gas or LPG (Liquefied petroleum) and steam. The reformed gas produced in the reformer consists of hydrogen, methane, carbon monoxide, carbon dioxide and water vapour. Carbon monoxide (CO) contained in the reformed gas has a poisoning effect on the electrode catalyst of the fuel ...
