Abstract
Official abstract text for this publication.
There are provided a hydrogen production apparatus, a fuel cell system and operation method thereof, which can more reliably suppress degradation due to oxidation of a catalyst in a hydrogen production apparatus even when start-ups and shutdowns are repeated without a purge operation during the shutdowns. The hydrogen production apparatus includes a reforming part, a shift reaction part, and a selective oxidation reaction part having a selective oxidation catalyst bed packed with a selective oxidation catalyst, wherein the hydrogen production apparatus has an oxygen absorbent bed packed with an oxygen absorbent capable of absorbing oxygen and capable of being regenerated by a reducing gas, and the oxygen absorbent bed and the selective oxidation catalyst bed are stacked with the oxygen absorbent bed on the downstream side, and the hydrogen production apparatus has means for opening the downstream of the oxygen absorbent bed to the atmosphere. The fuel cell system has this hydrogen production apparatus. The operation method of this fuel cell system includes opening the downstream of the oxygen absorbent bed to the atmosphere upon shutdown of the fuel cell system, and regenerating the oxygen absorbent using a hydrogen-containing gas during hydrogen production by the hydrogen production apparatus.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hydrogen production apparatus comprising a reforming part for obtaining a hydrogen-containing gas by utilizing a reforming reaction from a raw material for hydrogen production, a shift reaction part for reducing the concentration of carbon monoxide in the outlet gas of the reforming part by shift reaction, and a selective oxidation reaction part having a selective oxidation catalyst bed packed with a selective oxidation catalyst which selectively oxid…
