| Popis: | 107 In this study, the performance of proton exchange membrane-based electrochemical air dehumidification and humidification was investigated through experimental measurements. The membrane electrode assembly (MEA) for electrochemical dehumidification is comprised of one Nafion 117 membrane and two activated carbon electrode supported platinum catalyst. The air is dehumidified and humidified through the electrolysis of water vapor and electro-osmotic drag. Under the different temperature/humidity and operating conditions, the dehumidifying/humidifying rate and energy efficiency were discussed. The results revealed that the dehumidifying rate and energy efficiency are greatly improved through forced convection. At the condition of 30℃/80%RH, the dehumidifying rate of ~120g/m2h, the energy efficiency factor of ~0.055kg/kWh were obtained. The dew point below 0℃ can be achieved. Further, a micro-environmental chamber with electrochemical humidity control was developed by the integration of Ardunio microcontroller broad, humidity sensor, and two MEAs. |
