Abstract
【解決手段】固体酸化物燃料電池の流れフィールドプレートにある流路36の一方の壁を形成する流れフィールド38において、流れフィールドは、形状の異なる流れ障壁52、64、66のパターン化アレイを有する平坦な基板40を含み、流れ障壁は、基板から流路の内部へ突出する。流れフィールドの流路の横断面の面積は、流れの方向に減少し、形状の異なる流れ障壁は、丸形流れ障壁及び楕円形流れ障壁52、64、66を含む構造。
【選択図】図2
Description
酸素イオン電解質を使用する固体酸化物燃料電池の通常の動作中、オキシダント中の酸素は、カソードにおいて電気化学的に還元され、通常、その結果、酸素イオンと電子が生成される。酸素イオンは、反応場所から電解質を介して伝導され、アノードで燃料と電気化学的に反応して、H2O及びCO2を形成する。更に、採用される燃料に応じて、他の種が生成される可能性もある。
