Solid polyelectrolyte, assembly of membrane and electrodes, and fuel cell |
摘要 |
An object of the present invention is to provide a highly durable solid polymer electrolyte that has a deterioration resistance equal to or higher than that of the fluorine-containing solid polymer electrolytes or a deterioration resistance sufficient for practical purposes, and can be produced at a low cost. According to the present invention, there is provided a solid polymer electrolyte comprising a polyether ether sulfone that is used as a electrolyte and has sulfoalkyl groups bonded to its aromatic rings and represented by the general formula -(CH<SUB>2</SUB>)<SUB>n</SUB>-SO<SUB>3</SUB>H.
