Description
また、遮蔽部材は、前記位置に設定した換気用ガス導入口および換気用ガス排出口の少なくともいずれか一方の前記ケース内の空間への開口に一端を接続したパイプ部材で構成し、このパイプ部材の前記ケース内の空間への他端の開口を、前記燃料電池とは異なる方向に向けたので、外部から換気用ガス導入口や換気用ガス排出口を経てケース内へ浸入する水は、パイプ部材を流れてケースの下部に落下し、燃料電池への接触を防止でき、燃料電池からケースに水が流れ落ちることにより発生する瞬間的な絶縁抵抗の低下を防止することができる。
3 ケース
5 燃料電池外周の空間
9 換気用ガス導入口
9a 換気用ガス導入口のケース内の空間への開口
11 換気用ガス排出口
11a 換気用ガス排出口のケース内の空間への開口
13,15 遮蔽板(遮蔽部材)
17,19 パイプ部材(遮蔽部材)
17a,19a パイプ部材のケース内の空間への他端の開口
Claims (4)
- 燃料電池を、この燃料電池とは電気的に絶縁したケース内に収容し、前記燃料電池外周の前記ケース内の空間に連通する換気用ガス導入口および換気用ガス排出口の少なくともいずれか一方を、前記燃料電池に対し、鉛直方向上方位置もしくは同等位置に設定し、この位置に設定した前記換気用ガス導入口および換気用ガス排出口の少なくともいずれか一方から前記ケース内に浸入する水を、前記燃料電池に対して遮蔽するとともに、前記燃料電池に対して電気的絶縁状態とする遮蔽部材を設け、この遮蔽部材は、前記位置に設定した換気用ガス導入口および換気用ガス排出口の少なくともいずれか一方の前記ケース内の空間への開口に一端を接続したパイプ部材で構成し、このパイプ部材の前記ケース内の空間への他端の開口を、前記燃料電池とは異なる方向に向けたことを特徴とする燃料電池のケース構造。
- 前記パイプ部材の前記ケース内の空間への他端の開口を、鉛直方向下方に向けたことを特徴とする請求項1記載の燃料電池のケース構造。
- 燃料電池を、この燃料電池とは電気的に絶縁したケース内に収容し、前記燃料電池外周の前記ケース内の空間に連通する換気用ガス導入口および換気用ガス排出口の少なくともいずれか一方を、前記燃料電池に対し、鉛直方向上方位置もしくは同等位置に設定し、この位置に設定した前記換気用ガス導入口および換気用ガス排出口の少なくともいずれか一方を、鉛直方向上方に向けて外部に開口させるとともに、前記空間に向かう開口方向を、前記燃料電池とは異なる方向としたことを特徴とする燃料電池のケース構造。
- 前記位置に設定した換気用ガス導入口および換気用ガス排出口の少なくともいずれか一方を、前記ケースの上面で、かつ前記燃料電池に対して水平方向にずれた位置に接続したことを特徴とする請求項3記載の燃料電池のケース構造。
