HYDROGEN PRODUCTION APPARATUS AND FUEL CELL POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen production apparatus capable of accurately measuring the temperature of a refining catalyst layer from the detection temperature of a refining gas, and also of accurately obtaining the catalyst layer temperature even when restarting an operation by re-combustion in a heating means after operation stop.

SOLUTION: The hydrogen production apparatus is provided with: a refining catalyst layer 3 for generating a hydrogen-rich refined gas from a raw material and moisture; a refined gas concentration part 5 which is provided at the downstream side of the refined gas flow from the refining catalyst layer 3 and concentrates such gas flow; and a temperature detection means 6 for detecting the temperature of the refined gas passing through the concentration part 5. The apparatus is further provided with: a data storage part 7 for storing the relation data of the observed temperature value of the refining catalyst layer 3 corresponding to the detection temperature value of the refined gas in the concentration part 5 which is detected by the temperature detection means 6 when the temperature of the catalyst layer 3 is at the observed value; and a calculation part 8 for calculating the temperature of the catalyst layer 3 from that detected by the temperature detection means 6 on the basis of the above corresponding relation data stored in the data storage part 7.
