Abstract | The present invention relates to a fuel cell membrane humidifier which adjusts a clearance between hollow fiber membranes according to a temperature of a fluid flowing between the hollow fiber membranes to improve humidification efficiency. A fuel cell membrane humidifier according to an embodiment of the present invention comprises: a mid-case; a cap fastened to the mid-case; a plurality of hollow fiber membranes disposed in the mid-case and exchanging moisture with an air supplied from the outside and flue gas introduced from a fuel cell stack to humidify the air; and a clearance adjustment pipe disposed between the plurality of hollow fiber membranes and formed of a material having a thermal expansion coefficient different from that of the plurality of hollow fiber membranes, so as to adjust the clearance between the plurality of hollow fiber membranes according to a temperature of flue gas.
La présente invention concerne un humidificateur à membrane de pile à combustible qui ajuste un espacement entre des membranes à fibres creuses en fonction d'une température d'un fluide s'écoulant entre les membranes à fibres creuses pour améliorer l'efficacité d'humidification. Un humidificateur à membrane de pile à combustible selon un mode de réalisation de la présente invention comprend : un boîtier central ; un capuchon fixé au boîtier central ; une pluralité de membranes à fibres creuses disposées dans le boîtier central et échangeant de l'humidité avec un air apporté depuis l'extérieur et du gaz de combustion introduit à partir d'un empilement de piles à combustible pour humidifier l'air ; et un tuyau d'ajustement d'espacement disposé entre la pluralité de membranes à fibres creuses et formé d'un matériau présentant un coefficient de dilatation thermique différent de celui de la pluralité de membranes à fibres creuses, de manière à ajuster l'espacement entre la pluralité de membranes à fibres creuses en fonction d'une température de gaz de combustion.
본 발명은 중공사막들 사이에서 유동하는 유체의 온도에 따라 중공사막들 사이의 공극을 조절하여 가습 효율을 향상시킬 수 있는 연료전지 막가습기에 관한 것으로, 본 발명의 실시예에 따른 연료전지 막가습기는, 미드-케이스; 상기 미드-케이스와 체결되는 캡; 상기 미드-케이스 내에 배치되며, 외부로부터 공급되는 공기와 연료전지 스택으로부터 유입된 배가스와 수분 교환하여 상기 공기를 가습하는 복수의 중공사막들; 및 상기 복수의 중공사막들 사이에 배치되고, 상기 복수의 중공사막들과 열팽창율이 다른 물질로 형성되어 상기 배가스의 온도에 따라 상기 복수의 중공사막들 사이의 공극을 조절하는 공극 조절관;을 포함한다. |
