Description
上記目的は、燃料電池と、前記燃料電池から排出された燃料オフガスを吸入する吸入口、燃料ガスを前記燃料オフガスと共に前記燃料電池に供給する吐出口、を含むエジェクタと、前記エジェクタよりも重力方向側に位置し、前記エジェクタに供給される前の前記燃料オフガスから水分を分離して貯留する気液分離器と、前記エジェクタの吐出口と前記燃料電池を連結した第１配管と、前記エジェクタの吸入口と前記気液分離器を連結した第２配管と、前記エジェクタの内部を介して前記第１配管側から前記第２配管側に延びた排出流路と、を備え、前記排出流路は、一端に形成された第１開口端と、他端に形成された第２開口端とを有し、前記第１開口端から前記第２開口端までの間では密閉された空間を画定し、前記第１開口端は、前記第１配管内で開口し、前記第１配管と前記エジェクタとの接続部の下端に位置し、前記第１及び第２開口端は、前記排出流路の前記第１開口端と前記第２開口端との間の部位の少なくとも一部よりも重力方向側に位置している、燃料電池システムによって達成できる。前記第２開口端は、前記第２配管内又は前記気液分離器内に位置して、前記第１開口端よりも重力方向側に位置してもよい。前記排出流路は、前記エジェクタの一部の切り欠きにより形成されていてもよい。前記排出流路の内部表面には、親水処理が施されていてもよい。 The above object is an ejector including a fuel cell, a suction port for sucking fuel off gas discharged from the fuel cell, and an discharge port for supplying fuel gas to the fuel cell together with the fuel off gas, and a direction of gravity from the ejector. A gas-liquid separator located on the side that separates and stores water from the fuel off gas before being supplied to the ejector, a first pipe connecting the discharge port of the ejector and the fuel cell, and the ejector. The discharge flow path includes a second pipe connecting the suction port and the gas-liquid separator, and a discharge flow path extending from the first pipe side to the second pipe side via the inside of the ejector. It has a first open end formed at one end and a second open end formed at the other end, and defines a closed space between the first open end and the second open end. The first open end is opened in the first pipe and is located at the lower end of the connection portion between the first pipe and the ejector, and the first and second open ends are the first of the discharge flow paths. This can be achieved by a fuel cell system located on the gravity direction side of at least a portion of the portion between the one open end and the second open end. The second opening end may be located in the second pipe or in the gas-liquid separator and may be located on the gravity direction side of the first opening end. The discharge flow path may be formed by a notch in a part of the ejector. The inner surface of the discharge channel may be treated with hydrophilicity.
