有別於傳統空氣除濕過程中存在相變化與溫度變化,如冷凝除濕、固態除濕及溶液除濕,本研究針對無相變化的薄膜電化學除濕技術進行探討,除濕薄膜電極組(membrane-electrode-assembly, MEA)由一片Nafion 117質子交換膜及兩片擔載白金(Pt)觸媒之碳電極所組成,透過水電解及電滲透效應進行除濕及加濕程序。首先,在不同溫濕度及操作電壓條件下,本研究針對除濕(加濕)速度與除濕(加濕)能源效率進行探討。實驗結果顯示強制對流效應可大幅地將除濕速度提升近7倍,除濕能源效率提升3倍以上,在30℃/80%RH的環境條件下,除濕速度約為120g/m2h,除濕能源效率因子(Energy Efficiency Factor, EEF)約為0.055kg/kWh,露點溫度可達0℃以下。進一步地,本研究以Ardunio微控制板及濕度感測器,結合兩個質子交換薄膜電極組,製作出一個具質子交換膜電化學濕度控制的微環境箱。
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.
