Abstract: Membranes and methods of making and using the membranes are described herein. The membranes can include a foamed polymeric support and a plurality of inorganic particles disposed within the foamed polymeric support. The foamed polymeric support can contain a hydrophilic polymer such as polyethersulfone. The plurality of inorganic particles can include hydrophilic particles such as zeolite particles. In certain embodiments, the membrane can be used in humidifiers, such as those used in fuel cell systems. In some aspects, the membrane can be used for separating a fluid mixture comprising water. The membranes described herein are stable for high temperature applications.
