摘要:
A method and system for cooling an internal space are provided. A laminate of a hydrophobic membrane and a hydrophilic membrane includes a superabsorbent polymer disposed on or encompassing the hydrophilic membrane. The superabsorbent polymer increases the wicking capacity of the hydrophilic membrane so that water from a source is distributed more rapidly across the hydrophilic membrane. The distributed water is evaporated from the hydrophilic membrane, causing evaporative cooling of the laminate and surrounding air stream(s). The cooled air stream(s) are used to cool the internal space.
摘要:
A composite proton exchange membrane includes first and second outer proton exchange membrane layers each having an exterior peripheral portion. An inner proton exchange membrane layer is interposed between the first and second outer membrane layers. The inner membrane layer has an exterior peripheral portion encompassed within each of the outer membrane layer peripheral portions. A substantially fluid-impermeable edge bonding film is interposed between the first and second outer membrane layers. The edge bonding film circumscribes the inner membrane layer peripheral portion and is disposed within each of the outer membrane layer peripheral portions. The edge bonding film cooperates with the first and second outer membrane layers to encapsulate the inner layer.
