一种可用于燃料电池的聚乙烯醇阴离子交换膜的制备方法
摘要：
本发明公开了一种可用于燃料电池的聚乙烯醇阴离子交换膜的制备方法。该聚乙烯醇阴离子交换膜由聚乙烯醇(PVA)、正硅酸乙酯(TEOS)、戊二醛交联、并用KOH改性而制成，其中二氧化硅对聚乙烯醇的含量为5％-30％。本发明制备的聚乙烯醇阴离子交换膜具有较好的导电率、对乙醇具有较低的渗透率、对水具有较低的溶胀率，可用作碱性直接醇类燃料电池的电极膜和电极结合体中。
摘要（英）：

The invention discloses a preparation method for a polyvinyl alcohol anion exchange membrane for a fuel cell. The polyvinyl alcohol anion exchange membrane is prepared from polyvinyl alcohol (PVA), tetraethoxysilane (TEOS), and glutaraldehyde which is used for crosslinking, through KOH in a modification way, wherein content of silicon dioxide accounts for 5-30% of the polyvinyl alcohol. The polyvinyl alcohol anion exchange membrane prepared by the invention has relatively high conductivity, relatively low permeability on ethyl alcohol, relatively low swelling ration on water, and can be used in an electrode membrane and an electrode combination body of an alkali direct alcohol fuel cell.
