    摘要: A fuel processor system contains an autothermal reactor (ATR) that produces a hydrogen-rich first gas stream containing carbon monoxide. Downstream of the ATR, a pressure swing adsorber produces a second hydrogen-rich gas stream containing 5 ppm carbon monoxide or more. Downstream of the PSA, there is a methanation reactor sized to reduce the CO level of the second stream below 5 ppm. A method of operating of proton exchange membrane fuel cell stack involves cooling the methanator output and feeding it into the stack as an anode fuel.

    摘要: A water transfer device can include first and second flow paths separated by a water transfer membrane and a hydrophilic diffusion medium. The hydrophilic diffusion medium is disposed between the water transfer membrane and the first flow path. Water content of a first fluid stream flowing through the first flow path is transferred through the diffusion medium and water transfer membrane and into a second fluid stream flowing through the second flow path. The hydrophilic diffusion medium is operable to absorb liquid water in the first fluid stream and hold the absorbed liquid water in contact with the water transfer membrane. The hydrophilic diffusion medium is also operable to diffuse water vapor in the first fluid stream and transport the water vapor to the water transfer membrane. The water transfer membrane transfers the water in contact therewith to the second fluid stream flowing through second flow path.
