SOLID OXIDE FUEL BATTERY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a solid oxide fuel battery system which reduces the effect of air bubbles mixed into water to supply water to a fuel reformer.

SOLUTION: The solid oxide fuel battery system includes the fuel reformer 4 which steam reforms a raw fuel, a solid oxide fuel battery 6 which generates electric power through oxidation and reduction of a reformed fuel gas reformed by the fuel reformer 4 and an oxidant, and a water supply means 52 which supplies reforming water to the fuel reformer 4. The water supply means 52 includes a supply pump 80 which supplies water through a supply channel 78 and a water flow sensor 84 which detects a water flow. A pump controller counts the number of air bubbles mixed into water based on a detection signal from the water flow sensor 84, and generates an additional operation signal based on the resulting air bubble count to additionally operate the supply pump 80.
