システムの機能性が損なわれてはならない。
を例として示す。“実施例”もしくは“オプション(選択肢)”とも称されるこれらの実施形態は、当業者が本発明を実践できるように充分詳細に記載される。実施形態は組み合わされてもよく、他の実施形態が利用されてもよく、あるいは本発明の範囲から逸脱することなく、構造的もしくは論理的変更がなされてもよい。従って以下の「発明を実施するための形態」は、限定的な意味でとられるものではなく、本発明の範囲は添付の請求項とその法的均等物によって規定される。
本明細書で使用される“流体”という用語は、その分子が互いに自由に行き来し、その容器の形状をとる傾向があるような、途切れのない無定形物質のことをあらわす。流体は、気体、液化ガス、液体、もしくは加圧液体であってもよい。流体の実施例は、流体反応物質、燃料、酸化剤、および熱伝導流体を含んでもよい。燃料電池で使用される流体燃料は、水素の気体もしくは液体、および任意の適切な流体形態の水素担体を含んでもよい。流体の実施例は、空気、酸素、水、水素、メタノールやエタノールなどのアルコール、アンモニア、アミンやヒドラジンなどのアンモニア誘導体、ジシランやトリシランやジシラブタンなどのシラン類、水素化ホウ素アルミニウムなどの錯体金属水素化物化合物、ジボランなどのボラン類、シクロヘキサンなどの炭化水素、ドデカヒドロ-n-エチルカルバゾールなどのカルバゾール、および他の飽和環状炭化水素、飽和多環式炭化水素、シクロトリボラザンなどの飽和アミノボラン類、ブタン、水素化ホウ素ナトリウムや水素化ホウ素カリウムなどの水素化ホウ素化合物、およびギ酸を含む。
”もしくは“occluding”もしくは“occlusion”)”という用語は、流体などの物質の吸収もしくは吸着、ならびに保持をあらわす。例えば水素が吸蔵される流体であってもよい。流体は、例えば化学吸着もしくは物理吸着などによって、化学的もしくは物理的に吸蔵されてもよい。
チャージもしくは燃料補給できる。流体制御システム104は、下記でさらに説明するように、燃料の分布と調節を提供する。流体マニホルド120は、流体制御システム104と、燃料電池102と、燃料容器108との間に燃料用の導管を提供する。流体マニホルドはまた、限定はされないが熱伝導流体を含む、他の流体を分布させるためにも使用できる。
可撓性特徴は随意に弾性特性を持つ。可撓性特徴は一オプションでは第二の圧力プレナムに統合される。さらなるオプションでは、可撓性特徴は流体制御システム部品を通る流れを所定の範囲の知覚流体圧力の間に制限する。なおもさらなるオプションでは、バネ部材が可撓性特徴に接触する。
