  • Freeze tolerant fuel cell fuel pressure regulator
    Patent number: 10658686
    Abstract: A fuel pressure regulator unit is mounted on a manifold. The fuel pressure regulator unit includes a housing providing a fuel inlet passage, a regulated fuel outlet passage, a sense pressure passage, a recycle passage and a mixed fuel passage. A pressure regulator is provided in the housing and is arranged fluidly between the fuel inlet passage and the regulated fuel outlet passage. The sense passage fluidly interconnects the mixed fuel passage and the pressure regulator. The pressure regulator is configured to regulate the flow of fuel from the fuel inlet passage to regulated fuel passage in response to a pressure from the sense pressure passage. An ejector is arranged within the housing and fluidly between the regulated fuel outlet passage and the mixed fuel passage. An ejector is configured to receive recycled fuel from the recycle passage.
