Title:
SOLID OXIDE FUEL CELL SYSTEM
Document Type and Number:
Japanese Patent JP2016122583
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell system capable of suppressing oxidation of a fuel electrode by steam for preventing carbon deposition while preventing carbon deposition to the fuel electrode by raw fuel gas supply.SOLUTION: A solid oxide fuel cell system (1) comprises: a fuel cell module (2); an oxidant gas supply device (45); a reforming unit (20c); a fuel supply device (38); an evaporating unit (20a); a water supply device (28); an electromotive force sensor (126); and a controller (110) which performs a starting step and shutdown stop. The controller includes a water/fuel supply circuit (110a) which starts water supply or raw fuel gas supply in a temperature zone in which carbon deposition may occur. The water/fuel supply circuit controls the supply of water to be pre-supplied which is the total amount of water supplied during the period from when water supply is started to when raw material gas supply is started on the basis of the electromotive force measured by the electromotive force sensor.SELECTED DRAWING: Figure 12
