▎ 摘  要

NOVELTY - Anion exchange composite membrane comprises pores-containing substrate, alkaline polymer, and inorganic nano-materials arranged in the pores. The main chain of the alkaline polymer comprises an aryl group, a piperidone group and/or an imidazolone group. The side chain of the alkaline polymer comprises a quaternary ammonium group. USE - The anion exchange composite membrane is useful in an alkaline fuel cell, an alkaline water electrolyzer and a carbon dioxide reduction device (claimed). ADVANTAGE - The anion exchange composite membrane: has excellent stability, high ion exchange capacity, high hydroxide ion conductivity, low swelling degree, and excellent comprehensive performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing an anion exchange composite membrane, comprising pouring the mixed liquid of the alkaline polymer and the inorganic nano-materials into pores-containing substrate and drying to obtain final product.
