Description
例示的な構造
図1A〜図1Bは、一般にセラミック基材(110)上に形成された複数の個別の燃料電池(105)を備える、燃料電池層(100)の平面図及び下面図を示している。各燃料電池は、基材(110)上に形成された燃料極、空気極及び電解質を備える。電解質は、基材(110)の非活性部をシールするために用いることができる。燃料電池層(100)は、空気極側(図1Aの115)と燃料極側(図1Bの120)の2つの相対する面を有する。
例示的な実施形態及び動作
図2A及び2Bは、複数の燃料電池層(図1A及び図1Bの100)を集めた燃料電池システム(200)の上面図並びに下面図を示している。燃料電池層(100)は、基盤(210)と蓋(220)との間に収容されている。基盤(210)は、空気及び燃料の経路指定部材を備える。新しい空気極空気は、空気極空気入口(230)を介してシステムに導入され、過剰な空気極空気は、過剰空気極空気出口(240)を介して排出される。燃料は、燃料入口(250)を介してシステムに導入され、過剰の燃料及び副生物は、燃料排出口(260)を介して排出される。後でより詳しく説明するように、空気極空気入口(230)、空気極空気出口(240)、燃料入口(250)、及び燃料排出口(260)の各々は、システム(200)を構成する各燃料電池層(100)の対応する入口及び出口に流体連通している。
代替実施形態
図5は、個別の燃料電池(105)を空気極側(120a)に形成し、燃料電池スタック(145a)が構成されている、燃料電池層(100a)を示している。燃料電池スタック(145a)は、平面アレイとし得る。この実施形態では、燃料電池(105)の空気極が基材(110a)の最も近くに形成され、燃料極が外側にある。さらに、正極導体(150a)は、燃料電池スタック(145a)に接続され、燃料入口(165a)につながっている。また、負極導体(155a)は、燃料電池スタック(145a)と出口(170a)に接続されている。したがって、この実施形態では、燃料極側(115)は、燃料電池層(100a)の回路側として機能する。
