A dual layer of Polymer electrolyte membranes with water generation at catalytic/interfacial layer for a self- humidification system. |
| 초록 |
The electrochemical behavior of this junction could be compared to a semiconductor-like p–n junction where the mobile positive carriers in the PEM are hydrogen ions and the mobile negative carriers in the AEM are hydroxide ions, respectively. This sandwiched structure of polymer matrix is a hybrid material which facilitates the self-humidification at the connected position as well generation of H+ and OH- for the formation of H2O. In present work, we have prepared CMSP (BPM) with using sulfonated poly (1,4-phenylene ether-ether-sulfone) (SPEES) an acidic layer while quaternized polysulfone (QPS) for the alkaline layer. QPS was prepared with chloromethylated polysulfone and the dilute solution of SPEES and QPS using for the interfacial layer for novel BPM preparation. This BPM interface effectively acts as a self-humidification due to the transportation of H+ and OH- from anode and cathode respectively. |
