Abstract

The invention discloses a fuel cell composite valve, which opens and closes the inflow pipeline and the discharge pipeline of a fuel cell stack for a hydrogen fuel cell vehicle. The fuel cell composite valve includes a support frame with a first One hole and a second hole, the discharge line is connected to the first hole and the inflow line is connected to the second hole. The first rotary valve is configured to receive a driving torque of a driving motor installed in the support frame, rotate the first rotary valve, and open and close the first hole. The second rotary valve is connected to the first rotary valve, and the second rotary valve is configured to open and close the second hole. The first coupler protrusion protrudes from the first shaft in a longitudinal direction, and the first coupler protrusion has at least one first planar surface perpendicular to the longitudinal direction. A second coupling protrusion protrudes from the second shaft in a longitudinal direction of the first shaft.

Description

[0001] Cross-references to related applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2014-0060845 filed with the Korean Intellectual Property Office on May 21, 2014, the entire contents of which are hereby incorporated by reference. technical field [0003] The inventive concept relates to a fuel cell compound valve for a vehicle, which can integrally form a valve that selectively opens and closes a fuel cell stack mounted on a fuel cell vehicle Air inflow lines and air discharge lines at the front and rear ends of the Background technique [0004] Generally, there are two types of valves in the air supply system of a fuel cell vehicle. [0005] One type of valve is an air cutoff valve that selectively cuts off the air at the front end and the rear end of a fuel cell stack, which is a hydrogen Chemical reaction device. Another type of valve is a back pressure regulating valve installed at the rear end of the fuel cell...
