Abstract
【解決手段】燃料電池10と、燃料電池10から排出された燃料オフガスを燃料電池10から排出された酸化オフガスに希釈させて外部に排出させる希釈器21と、燃料電池10と希釈器21との間を接続する燃料オフガス流路32と、燃料オフガス流路32に設けられて開動作時に燃料オフガス流路32を流通する燃料オフガスを外部へと排出するための排出弁37と、を備えた燃料電池システム1であって、排出弁37が希釈器21に一体に取り付けられている。
【選択図】図2
Description
したがって、別個の保温システムを備えた場合と比較し、装置の大型化を抑制しつつ低温時における排出弁の凍結を解消することができる。
また、この希釈器21における排気路51の近傍には、取付口52が形成されており、この取付口52には、排気排水弁37の取付部37aが差し込まれて取り付けられている。つまり、本実施形態では、排気排水弁37が希釈器21に一体に取り付けられた構造とされ、排気路51を形成する排出案内部50の壁部51aのうち排気排水弁37の取付部37aが差し込まれる側の壁部51aと、取付口52を形成する壁部52aのうち排気路51側の壁部52aとが一体化した構成とされている。なお、これら壁部51aと壁部52aとが別々(別体)に構成されている場合には、これら壁部51a,52aが互いに当接した状態で接続される。
したがって、別個の保温システムを備えた場合と比較し、装置の大型化を抑制しつつ低温時における排気排水弁37の凍結を解消することができる。
また、排気路51の内壁と排気排水弁37との間に少なくとも排出案内部50の壁部51a及びこれと一体をなす取付口52の壁部52aよりも熱伝導率の高い熱伝導部材53を介在させた構造であるため、排気排水弁37への熱の伝達を熱伝導部材53によってさらに良好に伝達させることができる。
Claims (3)
