Abstract: Improved three way valves comprise three openings aligned to directly connect with a corresponding series of ports and a selectively positionable seal that regulates the flow of a fluid within the valve. Improved fuel cells comprise a plurality of flow channels connected to at least one improved three way valve suitable for regulating fluid flow through the fuel cell. Generally, the flow channels comprise a series of ports, wherein the three way valve is configured to engage and disengage from the series of ports directly to form a manifold without the use of additional connectors, for example, tubes and/or hoses. Due to the fact that the three way valve can engage and disengage form the series of ports directly, potential leakage points in the fuel cell piping system can be reduced. In some embodiments, the three way valve comprises a central chamber having a selectively positionable seal, a bypass chamber and a through chamber. Generally, the selectively positionable seal can form a seal selectively at the port, or passage, connecting the central chamber with the bypass chamber or with the through chamber. The selectively positionable seal can regulate fluid flow from the central chamber to the bypass chamber and to the through chamber.

Abstract: Improved three way valves (100) comprise three openings (108, 110, 112) aligned to directly connect with a corresponding series of ports and a selectively positionable seal that regulates the flow of a fluid within the valve. Improved fuel cells comprise a plurality of flow channels connected to at least one improved three way valve suitable for regulating fluid flow through the fuel cell. Generally, the flow channels comprise a series of ports, wherein the three way valve is configured to engage and disengage from the series of ports directly to form a manifold without the use of additional connectors, for example, tubes and/or hoses. Due to the fact that the three way valve can engage and disengage form the series of ports directly, potential leakage points in the fuel cell piping system can be reduced. In some embodiments, the three way valve comprises a central chamber (102) having a selectively positionable seal, a bypass chamber (104) and a through chamber (106). The selectively positionable seal can regulate fluid flow from the central chamber to the bypass chamber and to the through chamber.

Abstract: A flow controller includes a body having an inlet end, an outlet end, a flow measurement portion, a variable valve portion and a control portion to control the valve portion based on an output from the flow measurement portion. The flow measurement portion includes a pair of differential pressure sensors for measuring the pressure drop across a flow path as the fluid flows through the flow path. The flow control portion comprises a flexible tube and a plunger with a motor drive that incrementally pinches the flexible tube. A linear, constant diameter bore extends through the housing forming a fluid flow passage for providing a calibrated pressure drop to a fluid that is passed through the fluid flow passage. A replaceable portion of the fluid flow passage is comprised of resilient soft plastic tubing as part of a pinch valve having non-contaminating fittings for positive device shut off.
