To provide a fuel battery system that can appropriately inhibit detection of fuel leakage from being performed using a pilot flame registration function of a gas meter while making a solid oxide type fuel battery operate continuously and can make the solid oxide type fuel battery operate appropriately while using the pilot flame registration function of the gas meter.SOLUTION: An operation control section C is configured to execute an abnormality avoidance mode, in which a predetermined amount of fuel set by increasing/decreasing a setting reference flow rate corresponding to a setting flow rate on the basis of a setting change condition is supplied to a fuel battery 1 on the basis of a detection result of a mass type flow rate measurement section Fa, over a mode execution time determined to be longer than a predetermined time in a predetermined period; and is configured to control an output adjustment section 12 so as to increase output of a cell stack ST in the case that a fuel supply amount to the fuel battery 1 is large as compared with that in the case that the fuel supply amount is small, in executing the abnormality avoidance mode.SELECTED DRAWING: Figure 1 【課題】固体酸化物形の燃料電池を連続して運転させながらも、ガスメータの口火登録機能を利用して燃料漏れの検出が行われことを的確に回避し、しかも、ガスメータの口火登録機能を利用しながらも、固体酸化物形の燃料電池を適切に運転させることができる燃料電池システムを提供する。【解決手段】運転制御部Ｃが、設定流量に対応する設定基準流量を設定変化条件に基づいて増減変化させて設定した所定量の燃料を、質量式流量計測部Ｆａの検出結果に基づいて燃料電池１に供給する異常回避モードを、所定期間中において、所定時間よりも長く定めたモード実行時間に亘って実行するように構成され、且つ、異常回避モードを実行する際に、燃料電池１に対する燃料の供給量が多いときには少ないときよりも、セルスタックＳＴの出力を増加させるべく、出力調節部１２を制御するように構成されている。【選択図】図１
