Preparation of anion-exchange membranes using polysulfone for alkaline solid polymer electrolyte fuel cells |
| 초록 |
Alkaline solid polymer electrolyte fuel cells (ASPEFCs) are a hybrid of polymer electrolyte membrane fuel cells (PEMFCs) and alkaline fuel cells (AFCs). PEMFCs use proton-conducting membranes, but ASPEFCs anion-exchange membranes (AEMs) as an electrolyte. In this regard, ASPEFCs using AEMs have several advantages when compared to PEMFCs and AFCs: i) use of non-noble catalysts as an electrode, ii) use of cheaper membranes, iii) simplified water management and iv) mitigation of CO2 contamination. In this study, AEMs were prepared from chloromethylated polysulfone (CMPSf) and a number of mono- and diamine compounds. The AEMs are prepared in two steps: i) introduction of chloromethyl-groups as substituents for aromatic nuclei to an aromatic polymer in the presence of a Friedel-Crafts catalyst ii) introduction of the basic groups into polymer by treatment with mono- and diamine which are N-trimethylamine (TMA) and N,N,N’,N’-tetramethylhexanediamine (TMHDA), respectively. The quaternization with diamines proceeds as a mono-reaction (mono-quaternization) and as a cross-linking reaction (bi-quaternization) in part. |
