Abstract
【解決手段】 第1のガス(H2)と第2のガス(Air)とを混合するためのガス処理装置であって、第2のガス(Air)を流通させるための流通路(110)、流通路(110)における第2のガス(Air)の流通方向とは非平行な方向から第1のガス(H2)を流通させるための流入口(104)を有し、流通路(110)の一部を密封するハウジング(101)を備える。ハウジング(101)に密封されている領域の少なくとも一部において、流通路(110)は第2のガス(Air)及び第1のガス(H2)を流出入させるための孔構造(111)を備えている。この構造によれば、孔構造が乱流を発生させるので、第1のガス(H2)と第2のガス(Air)との混合度が向上し、均一にガス濃度を低下させることが可能となる。
【選択図】 図4
Description
本発明の実施形態1は、電気自動車に搭載する燃料電池システムに用いるために適する希釈器に本発明のガス処理装置を適用したものである。特に、希釈すべき水素ガスを希釈媒体である空気の供給パイプの周辺において乱流を発生させ混合するガス処理装置に関する。以下の実施形態は本発明の一形態に過ぎず、本発明はこれに限定されずに適用可能である。便宜上、本発明にいう第1のガスとして水素ガスを例示し、第2のガスとして空気を例示する。
2H++2e―+(1/2)O2 → H2O …(2)
H2+(1/2)O2 → H2O …(3)
式(1)の反応を生じさせるために、水素タンク200は、内部に水素吸蔵合金を備えている。水素吸蔵合金は、加熱すると吸熱反応を通じて水素を放出し、冷却すると放熱反応を通じて水素を吸蔵するような性質を有している。水素タンク200は、図示しない熱交換システムによって所望の量の水素を放出するように制御可能に構成されている。
本発明の実施形態2は上記実施形態1の希釈器において、さらにガスの混合・希釈を促進するための流通路の構造の変形例に関する。図6に本実施形態2における希釈器の側面図を示す。図6に示すように、本希釈器100bはハウジング101内において、流通路110の一部に屈曲部112を備えている点で特徴がある。その他の構成については上記実施形態1と同様である。
上記実施形態1では空気オフガスの流通路を囲むハウジングに水素オフガスを流入させ流通路の周囲から水素オフガスを供給する構造であったが、本発明の実施形態3では空気オフガスの流通路内部に水素オフガスの流通路を配置した点に特徴がある。
