FLOW PATH INCORPORATED PEDESTAL, FUEL CELL POWER GENERATION SYSTEM USING THE PEDESTAL, AND METHOD OF CONTROLLING TEMPERATURE OF THE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a flow path incorporated pedestal incorporated with a flow path of a structure capable of efficiently controlling the temperature by preventing the moisture contained in the fuel gas and the oxidizing gas from being condensed, a fuel cell power generation system using the pedestal, and a method of controlling the temperature of the system.

SOLUTION: In this pedestal, a groove 53F forming a cooling water discharging flow path is disposed in proximity to a groove 53A forming a fuel gas feed path and a groove 53F forming a cooling water discharge path to thermally insulate or heat modified gas and air flowing through the grooves 53A and 53C by cooling water (hot water) flowing through the groove 53F. Also, a groove 53G forming a flow path for collected hot water is disposed in proximity to a groove 53D forming a fuel gas discharge path and a groove 53E forming an oxidizing gas discharge path to cool the discharged modified gas and air flowing through the grooves 53D and 53E by the collected hot water flowing through the groove 53G.
