摘要： A separation and/or humidification element that employs fibrous hollow membrane tubes is provided, which may be used for water vapor transfer between different gas streams in a fuel cell application, such as to humidify the reaction gas. At least one and typically two composite end caps encapsulate ends of a bundle of the fibrous hollow membrane tubes. Each composite end cap comprises adhesive (e.g. epoxy) and a preform such as a plastic annular shroud.

摘要： The present disclosure relates to a technology of preparing an anion exchange composite membrane including: a porous polymer support; and a polyfluorene-based anion exchange membrane or a polyfluorene-based anion exchange membrane having a cross-linked structure formed on the support, and applying the same to alkaline fuel cells, water electrolysis, carbon dioxide reduction, metal-air batteries, etc. The polyfluorene-based anion exchange composite membrane including a porous polymer support according to the present disclosure has remarkably improved mechanical properties, dimensional stability, durability, long-term stability, etc.
