This work characterizes and comparatively assess two cation exchange membranes (PSEBS SU22 and CF22 R14) and one bipolar membrane (FBM) in microbial electrolysis cells (MEC), fed either by acetate or the mixture of volatile fatty acids as substrates. The PSEBS SU22 is a new, patent-pending material, while the CF22 R14 and FBM are developmental and commercialized products. Based on the various MEC performance measures, membranes were ranked by the EXPROM-2 method to reveal which of the polymeric membranes could be more beneficial from a complex, H production efficiency viewpoint. It turned out that the substrate-type influenced the application potential of the membranes. Still, in total, the PSEBS SU22 was found competitive with the other alternative materials. The evaluation of MEC was also supported by analyzing anodic biofilms following electroactive bacteria's development over time.
这项工作描述并比较了两种阳离子交换膜（PSEBS SU22 和 CF22 R14）和一种双极膜（FBM）在微生物电解池（MEC）中的性能，这些 MEC 分别以乙酸盐或挥发性脂肪酸混合物作为底物。PSEBS SU22 是一种新型的专利待批材料，而 CF22 R14 和 FBM 是开发中和商业化的产品。基于各种 MEC 性能指标，使用 EXPROM-2 方法对膜进行了排名，以揭示从复杂的产氢效率角度来看，哪种聚合物膜更具应用潜力。结果表明，基质类型影响了膜的应用潜力。尽管如此，总的来说，PSEBS SU22 被发现与其他替代材料具有竞争力。通过分析随着时间的推移电活性细菌在阳极生物膜中的发展情况，对 MEC 进行了评估。
