About TailorMem
TailorMem is a spin off company of IMC Czech Academy of Sciences with a license for ion exchange membranes, manufactured under the brand name TailorMem Hollex, which are used in the electrochemical applications such as production of green hydrogen, fuel cell technology, CO2RR and solid state electrolyte in lithium ion batteries. Chemistry of Hollex membrane is “true” hydrocarbon based (no oxygen or other heteroatom in main chain), PFAS-free and completely without fluorine.
Thanks to more than 16 years of development, and the application of the latest scientific knowledge and optimization, these membranes offer extraordinary durability and long life, which gives them a significant competitive advantage. They can be produced on an industrial scale (width 60–100 cm).
- Anion exchange membranes
- Cation exchange membranes
Our Technology
TailorMem Hollex ADL 911 membranes are specially designed for use in AEM electrolysis for hydrogen production. Hydrogen is considered the fuel of the future, playing a key role in the transition to a low-emission economy.
Low degradation rate and use of non-PGM catalyst makes them ideal for the low CAPEX seasonal energy storage sector.
Our membranes are also customizable (thickness, reinforcement, functional group) to meet customer requirements, even for other electrochemical applications, whereas competitors typically offer only a limited selection of standardized membrane types. This tailored approach ensures optimal performance and higher efficiency in specific applications.
Tailoring the structure Hollex ADL 911 membrane can be adopted for CO2RR, solid state electrolyte in lithium batteries, redox flow batteries and other electrochemical processes like electrodyalisis (ED) and electrodeionization (EDI).

Projects
TailorMem membrane Hollex ADL 911 NR is based on block copolymer that has been developed in IMC CAS and UCTP (CZ). It was patented and licenced to TailorMem company.
This copolymer was sucessfully used for membrane preparation and functionalization and further optimized in NEWELY project for use in anion exchange membrane water electrolysis (AEMWE). This membrane has optimal water transport, high hydroxide (OH – ) conductivity and high chemical stability in alkaline environment.
The milestone of NEWELY project (2V@ 1A/cm²) was outperformed with (1.5 A/cm² @2V) in 0.1 M KOH at 50°C with dry cathode with only 3 mg/cm² of non-PGM OXYGN-N and H2GEN-M on the anode and the cathode side, respectively, assembled in a CCS-like MEA with a 60μm thick membrane. More at Newely.eu.
This project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (now Clean Hydrogen Partnership) under Grant Agreement No 875118. This Joint Undertaking receives support from the European Union’s Horizon 2020 Research and Innovation program, Hydrogen Europe and Hydrogen Europe Research.
In 2024–2026, we are supported as part of the Technological Incubation project by CzechInvest, the business and investment development agency.
The project is focused on transitioning the production of homogeneous membranes from discontinuous batch type production to a continuous roll2roll process with the option of reinforcement and crosslinking. Cation exchange membrane is also being developed within this project.
