Description
従って、中空糸膜モジュール107では、中空糸膜106の内側に乾燥空気、外側に
湿潤空気が流れることになり、湿潤空気中の水分が中空糸膜106の外側から内側に移動して乾燥空気に水分が加えられ、加湿空気となって第1流出口103から出て、燃料電池(図示していない)に送られる。
燃料電池の加湿装置は、その内部に中空糸膜モジュールが内設され、この中空糸膜モジュールは、多数の中空糸膜が束にした形態で配置され、ブロワーなどにより外部から供給された乾燥空気は、中空糸膜内側を流れ、燃料電池スタックからの湿潤空気は、中空糸膜の外側を流れる。このとき、乾燥空気は中空糸膜の束の中央部に多く流れ、湿潤空気は中空糸膜の束の外周部に沿って多く流れようとしており、この形態そのものは従来の中空糸膜加湿装置と同じである。
第2中空糸膜12は、相対的に親水性が低い材料でなり、従って乾燥空気に対する加湿性能は第1中空糸膜11より劣るが、水分による膨潤が少ない材料で、ポリエーテルイミド、ポリフェニルスルホンなどが使用できる。
すなわち、中空糸膜の束の中央部では、ブロワーにより供給された外気、即ち乾燥空気は多いが、燃料電池スタックからの湿潤空気は少ないので、その少ない湿潤空気から効率よく水分を受取ることができるように相対的に親水性が高い材料である第1中空糸膜11を配置する。
すなわち、中空糸膜の束の外周部は、湿潤空気は多いが、乾燥空気は少ない環境にあるので、相対的に親水性が低い材料である第2中空糸膜12を配置する。
