Description
セル間冷媒プレートを使用し、かつグリコールまたは他の冷媒を含むシステムは、非常に小さいセル内水通路を備えてもよく、この通路によって、水流による冷却をあまり使用せずに水和させるために、燃料セルのアノード側に低流量の水を供給する。
高透過性層100の使用によって、水が非常に低流量の際に空気の気泡が水通路を妨害するという問題を防止するので、水通路は他の構成から成ってもよい。
Claims (11)
- 閾流量以下では、冷媒流通路(77,85)内の冷媒流において気泡(87,99)による妨害が生じ得る燃料セルにおいて前記閾流量未満の流量の冷媒を通流させる方法であって、
前記燃料セルの平面形状の実質的に全面に亘って延びる冷媒通路を設け、該冷媒通路の長さの実質的に全長に沿って、(a)ガスが前記通路内に存在する場合、および(b)ガスが該通路内に存在しない場合、の両方で前記燃料セルの前記冷媒通路内を流れる液体冷媒を気泡が妨害することを防止するように冷媒通路を構成することを特徴とする燃料セルにおいて使用される前記方法。 - 前記燃料セルの反応ガス流れ場プレート(75,81)の(a)内部および/または(b)これに隣接して、前記燃料セルの平面形状の実質的に全面に亘って延びる前記冷媒流通路内の冷媒通路(77,85)を設け、前記冷媒通路は、該通路内におけるガスの有無にかかわらず、該通路内の冷媒が流れるように構成されることを特徴とする請求項1に記載の方法。
- 前記冷媒通路(77,85)に、ガスが移動し流れ易い性質を有する第1の部分を設け、前記第1の部分は、ガスが前記性質を備えていない前記通路の第2の部分よりも優先的にガスが移動し流れることを特徴とする請求項1に記載の方法。
- ガスを冷媒から分離するという十分な傾向を備えた第1の部分を設けることで、前記通路内に存在するガスが、このような傾向を有していない前記通路の第2の部分よりも優先的に前記第1の部分へ移動して流れ、これにより、ガス気泡による前記冷媒通路の妨害を緩和するように、前記冷媒通路(77,85)を構成することを特徴とする請求項1に記載の方法。
- 燃料セル(38)の冷媒流通路(77,85)内の冷媒流においてガス気泡(87,99,131,132)による冷媒の妨害が生じ得る気泡妨害閾流量以下の流量で冷媒を通流させる方法であって、
