堿性膜燃料電池在燃料電池實踐中應用不多，膜的耐久性不高，空氣中的二氧化碳的吸附形成碳酸鹽，同時膜的離子電導率下降，但是阻止不了科學家們的探索，是發文章的熱門領域，其價值在于催化劑可以不用鉑，雙極板腐蝕問題有所緩解。
二氧化碳之于堿性膜就像一氧化碳之于酸性膜，一樣需要清除。

文章標題中的短路不是我們平常意義中的穿孔，氣體擴散層穿刺之類的，而是把碳材料扎扎實實做在膜里，讓多層膜內有的層有離子電導，有的層有電子電導。
視頻中可以觀察到二氧化碳濃度的下降。
Abstract
The alkaline environment of hydroxide exchange membrane fuel cells （HEMFCs） potentially allows use of cost－effective catalysts and bipolar plates in devices． However， HEMFC performance is adversely affected by CO2 present in the ambient air feed． Here， we demonstrate an electrochemically driven CO2 separator （EDCS） to remove CO2 from the air feed using a shorted membrane that conducts both anions and electrons． This EDCS is powered by hydrogen like a fuel cell but needs no electrical wires， bipolar plates or current collectors， and thus can be modularized like a typical separation membrane． We show that a 25?cm2 shorted membrane EDCS can achieve ＞99％ CO2 removal from 2，000?standard cubic centimetres per minute （sccm） of air for 450?hours and operate effectively under load－following dynamic conditions． A spiral－wound EDCS module can remove ＞98％ CO2 from 10，000?sccm of air． Our technoeconomic analysis indicates a compact and efficient module at ＞99％ CO2 removal costs US＄112 for an 80?kWnet HEMFC stack．
這篇文章給堿性膜的美國Versogen公司做了一個好廣告。要知道DOE燃料電池成本目標是15美元／kWnet，也就是1200美元，而這片文章通過計算說他們的二氧化碳移除裝置112美元就可以實現，堿性膜電堆也很便宜。這下Strategic Analysis有的忙了，明年把堿性膜燃料電池的成本分析也計算一下吧：P。
這里112美元不是說二氧化碳移除裝置＋電堆。
猛一看標題以為講的是燃料電池，或者是二氧化碳加氫，實際講的是二氧化碳電化學分離，從空氣中轉移到氫氣中在從尾排管排放到空氣中，二氧化碳沒有富氫轉化，二氧化碳沒有被電化學轉化成含氧化合物，如果是個電化學反應器進一步轉化就更有趣了。
作者的標題實際說的是氫氣輔助二氧化碳電化學分離，Brian Setzler給DOE的報告就是
Electrochemically－Driven Carbon Dioxide Separation
但是這么寫估計就沒有那么大的轟動效應了。
