Description
Claims (3)
- 流れ場にわたる均一の流れ分布を有するように燃料電池プレート流れ場を製造する方法であって、
流れ場と連通した入口マニホールドを設けるステップであって、前記流れ場が、第1のチャネルと、該第1のチャネルの両側に配置された第2のチャネルとを有する複数のチャネルを備え、前記第2のチャネルが、前記入口マニホールドから、前記第1のチャネルよりも制限された流体流を受ける、入口マニホールドを設けるステップと、
前記第1のチャネルと前記第2のチャネルとの間の相対的な圧力降下によって両者の間に圧力降下特性がもたらされるステップと、
前記圧力降下特性に応答して前記入口マニホールドからの流体流を前記第2のチャネルへ通流させ、前記第1のチャネルと前記第2のチャネルとの間の流れ分布を均一化するステップと、
を含み、
前記圧力降下特性が、前記第1のチャネルの長さL(ただし、Lは第1のチャネル長未満)にわたる浅いチャネル部分を備え、該浅いチャネル部分は、前記第2のチャネルの第1のチャネル深さよりも小さい第2のチャネル深さを提供することを特徴とする方法。 - 前記設けるステップは、第1の幅を有した前記入口マニホールドと、該第1の幅よりも大きい第2の幅を有した前記流れ場と、該第2の幅にわたって配置された前記流れ場へ向かう入口とを含むことを特徴とする請求項1に記載の方法。
- 前記設けるステップは、長さに沿って互いに平行に延びる前記第1のチャネルおよび前記第2のチャネルを含むことを特徴とする請求項2に記載の方法。
