Description
最初に、本発明の一実施形態に係る燃料電池装置の概略構成について図1を用いて説明する。図1は、本発明の一実施形態に係る燃料電池装置の概略構成を示す模式図である。
次に、本発明の一実施形態に係る燃料電池装置1で行われる発電動作及び再生(還元)動作の詳細について図2を用いて説明する。尚、図2において図1と同一の部分には同一の符号を付す。図2(a)〜図2(d)は、本発明の一実施形態に係る燃料電池装置1で行われる発電動作及び再生動作の流れを示す模式図である。
発電動作の前状態では、図2(a)に示すように、空気供給口109及び空気排出口110がともに閉じられており、燃料電池本体10の空間部111には、水素(H2)が封入されている。
H2+O2−→H2O+2e− …(1)
4H2O+3Fe→4H2+Fe3O4 …(2)
図2(c)に示した発電動作停止状態から、図2(d)に示すように、還元制御部30により燃料電池本体10の燃料極102と空気極103の間に電圧を印加し通電すると、燃料極102では、空間部111に残留している水(H2O)と通電により供給された電子(e−)とで下記の化学反応式(3)に示す電気分解が生じ、その電気分解により水素(H2)が発生する。
H2O+2e−→H2+O2− …(3)
4H2+Fe3O4→4H2O+3Fe …(4)
次に、上記の発電動作が行われる際に実行される温度制御部20の制御動作の詳細について、図1、図3、及び図4を用いて説明する。図3は温度制御部20の制御動作の一例を示すフローチャートであり、図4はヒータ通電停止タイミングを示す図である。
