CATALYST ELECTRODE LAYER AND METHOD FOR PRODUCING SAME

摘要

[Problem] To provide a catalyst electrode layer which has excellent durability and is easily controlled with respect to the cross-linking degree. [Solution] Provided is a catalyst electrode layer which is characterized by containing a catalyst for electrodes and an anion-conducting elastomer that is obtained by introducing a quaternary base-type anion exchange group into at least some aromatic rings in a copolymer of an aromatic vinyl compound and a conjugated diene compound or in a copolymer that is obtained by saturating some or all of the double bonds in the main chain by hydrogenating the conjugated diene part of the above-mentioned copolymer, in said anion-conducting elastomer, at least some quaternary base-type anion exchange groups forming a cross-linked structure.
