Back pressure control apparatus for fuel cell system |
摘要 |
A back pressure control apparatus used in a fuel cell system, which can normally operate even when the system starts in a low-temperature environment. The valve has a simple structure realized at low cost. The valve comprises a pipe member which functions as a portion of an oxidizing gas passage and is arranged along an approximately horizontal direction, where a predetermined area of the inner surface of the pipe member is subjected to a hydrophilic process in advance; and a valve element which is provided in the pipe member and is rotatable around a shaft, where the shaft is arranged in a cross-sectional direction of the pipe member. The pipe member may be arranged along an approximately vertical direction. In this case, a predetermined area of the inner surface of the pipe member is subjected to a water repellent process.
