| description | To provide a fuel cell system capable of securing a proper operation when started and suppressing a decrease in operation efficiency, and a method for controlling the fuel cell system.SOLUTION: A fuel cell system 10 comprises a fuel cell stack 11, a fuel supply unit 17, a partial oxidation device 21, a steam reformer 23, a first temperature sensor 27a, a second temperature sensor 27b, a third temperature sensor 27c, and a control device 31. The fuel supply unit 17 supplies a raw fuel to the partial oxidation device 21 and the steam reformer 23. The partial oxidation device 21 and the steam reformer 23 supply a fuel to the fuel cell stack 11 by reforming at least a part of the raw fuel. The control device 31 controls a fuel flow rate in each device according to a difference between a target temperature in an operation mode of each device corresponding to a plurality of operation processes at the time of start and a temperature acquired by each of temperature sensors 27a, 27b, and 27c.SELECTED DRAWING: Figure 1
【課題】始動時の適正な作動を確保しつつ運転効率の低下を抑制することができる燃料電池システム及び燃料電池システムの制御方法を提供する。【解決手段】燃料電池システム１０は、燃料電池スタック１１と、燃料供給部１７と、部分酸化器２１及び水蒸気改質器２３と、第１温度センサ２７ａ、第２温度センサ２７ｂ及び第３温度センサ２７ｃと、制御装置３１とを備える。燃料供給部１７は原燃料を部分酸化器２１及び水蒸気改質器２３に供給する。部分酸化器２１及び水蒸気改質器２３は、原燃料の少なくとも一部を改質することによって燃料電池スタック１１に燃料を供給する。制御装置３１は、始動時の複数の運転工程に対応する各デバイスの動作モードでの目標温度と、各温度センサ２７ａ，２７ｂ，２７ｃによって取得される温度との差異に応じて各デバイスでの燃料の流量を制御する。【選択図】図１ |
