Claims (3)
- 間隔が規定された一対の荷重受け板の間にセルスタックユニットが配置されると共に、前記セルスタックユニットに積層方向の圧縮荷重を付加する加圧機構として、前記荷重受け板とセルスタックユニットとの間に、セラミックスからなる複数の角ばねが圧縮状態で分散配置されていることを特徴とする積層型燃料電池。
- 請求項1に記載の積層型燃料電池において、一対の荷重受け板を連結する複数本のタイロッドが一方の荷重受け板を貫通して突出し、その突出部に外嵌した状態で荷重受け板とタイロッド端部との間に、タイロッドよりも線膨張係数が大きい耐熱金属からなるスリーブが介装されている積層型燃料電池。
- 請求項1又は2に記載の積層型燃料電池において、複数の角ばねを挟む荷重受け板とセルスタックユニットとの対向面に、複数の角ばねの端部が嵌合する凹部が設けられている積層型燃料電池。
