Cellfion advances fuel cell humidifier development with dynamic testing at Fraunhofer and new patent milestone
We’re excited to share that Cellfion, in cooperation with in Stuttgart, has begun dynamic testing of our unique PFAS-free, cellulose-based membranes for use in fuel cell humidifiers.

The tests are designed to simulate the demands of industrial fuel cell systems and will provide important validation and performance data for Cellfion’s on-going customer projects.The common objective with the customers is that Cellfion’s membranes will industrially replace PFAS-based polymer membranes in the humidifier system programs already from 2027 and forward, thus meeting the upcoming market demands for PFAS-free systems.For this purpose, Cellfion has also filed a patent application for its membrane technology targeted towards e.g. fuel cell humidifiers. This patent family strengthens Cellfion's intellectual property portfolio, reinforcing its position in the development of advanced cellulose-containing materials for energy applications. Cellfion continues to focus on delivering high-performance, adaptable membrane solutions for the electrochemical energy sector. The company's commitment to innovation is reflected in its ongoing efforts to offer PFAS-free membranes that meet both performance and regulatory requirements.
