About TailorMem
TailorMem is a Czech company with a license for ion exchange membranes, manufactured under the brand name TailorMem Hollex, which are used in the production of green hydrogen and other electrochemical applications such as CO2RR and solid state electrolyte in lithium batteries.
Thanks to more than 12 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, continuously by the roll2roll process).
- Anion exchange membranes
- Cation exchange membranes
Our Technology
TailorMem Hollex membranes are specially designed for use in hydrogen fuel cells, making them ideal for the automotive industry and energy sector. Hydrogen is considered the fuel of the future, playing a key role in the transition to a low-emission economy.
Our membranes are also customizable to meet customer requirements, even for other electrochemical applications like lithium ion batteries, whereas competitors typically offer only a limited selection of standardized membrane types. This tailored approach ensures optimal performance and higher efficiency in specific applications.

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.
