1. An apparatus for humidifying input gas for a proton exchange membrane fuel cell stack, the apparatus comprising:

  • an input gas chamber integrated with a fuel cell stack, the input gas chamber comprising at least one wall, the input gas chamber having an input gas inlet that receives an input gas flow and an input gas outlet in fluid communication with the fuel cell stack;

    a water vapor chamber integrated with the fuel cell stack, the water vapor chamber comprising at least one wall, the water vapor chamber having a water vapor inlet and a water vapor outlet, the water vapor inlet receiving a water vapor flow from the fuel cell stack; and

    a water-selective membrane disposed between the input gas chamber and the water vapor chamber, the water-selective membrane forming a common wall between the input gas chamber and the water vapor chamber, the water-selective membrane configured to selectively diffuse water from the water vapor flow to the input gas flow.
