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 t o 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 fro m the series of ports directly to form a manifold without the use of additiona l 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) havi ng a selectively positionable seal, a bypass chamber (104) and a through chambe r (106). The selectively positionable seal can regulate fluid flow from the central chamber to the bypass chamber and to the through chamber.
