HYDROGEN GENERATOR, FUEL CELL SYSTEM, AND METHOD OF OPERATING SAME

摘要

A hydrogen generation apparatus (100) includes: a reformer (1) configured to generate a hydrogen-containing gas by causing a reforming reaction of a raw material; a combustor (2) configured to heat the reformer; and a controller (5) configured to set a controlled temperature of the reformer to a first temperature when an oxygen concentration in the raw material is in a first state where the oxygen concentration is relatively low, and change the controlled temperature of the reformer to a second temperature higher than the first temperature when the oxygen concentration in the raw material is in a second state where the oxygen concentration is relatively higher than the oxygen concentration in the first state.
