dc.description.abstract | 本實驗利用超音波霧化增濕有設備體積小、霧化霧滴緻密增濕均勻、易補水等優點,開發出ㄧ套超音波霧化系統,包含反應氣體加溫器、功率超音波霧化器以及超音波增濕瓶,並將模糊滑動平面控制理論與功率超音波霧化器結合。
有別於一般加濕方法無法主動式控制濕度,本實驗藉由所開發出的超音波霧化系統可自動調整霧化器驅動電壓進而改變霧化量,隨著霧化量的上升與減少,氣體的相對濕度也能即時變化,進而控制相對濕度。 在能控制相對濕度後,本實驗將相對濕度與質子交換膜燃料電池之電流密度輸出這兩者參數納為模糊化輸入,透過模糊滑動平面理論,計算出ㄧ理想模糊化輸出值,再應用於質子交換膜燃料電池的電流輸出端。實驗結果發現,在有納入控制機制的超音波霧化系統之下,能明顯改善未加入控制機制的超音波霧化系統造成質子交換膜燃料電池電流密度震盪與衰減的情形。 | zh_TW |
dc.description.abstract | This paper takes advantage of using ultrasonic atomizer devices is small, atomized droplets densification and humidifier uniformly, easy to supply water, and develops an ultrasonic atomization system, reaction gas heater, power ultrasonic atomizer and ultrasonic atomization bottle. Besides, combine fuzzy sliding surface control theory with power ultrasonic atomizer.
It’s different from the general humidifier which can’t control humidity proactively. The ultrasonic atomization system developed by this paper can automatically adjust atomizer driving voltage to change amount of atomization, with increase and decrease of amount of atomization , the relative humidity of gas can also changes immediately, so that we can control relative humidity. After we can control relative humidity , this paper takes relative humidity and PEMFC current density output into fuzzy input according to fuzzy sliding surface control theory to calculate an ideal fuzzy output and applied to the current output of proton exchange membrane fuel cell then. It was observed that we can improve the oscillation and decrease too much of PEMFC output with ultrasonic atomization system control mechanism compared to without control mechanism. | en |
