Development and manufacturing of forest-based membranes for electrochemical energy devices

Emerging technologies such as Proton Exchange Fuel Cells (PEMFCs) and Redox Flow Batteries (RFB) are expected to contribute to societys transition towards renewable energy.

However, these technologies use toxic, PFSA-based membranes which have caused serious ill effects on human health and the environment.

In fact, the overall health cost due to PFAS usage is estimated to be between 52 and 84 billion per year, as a result of this the EU is placing restrictions to ban the substances, which initial bans already commencing.

This has resulted in major companies such as 3M announcing to stop all production of PFAS-based materials by 2025, a decision worth 2 billion USD annually.

To overcome this, Cellfion has developed a bio-based, ion-selective membrane derived from natural cellulose, the first of its kind.

This innovation is 27 times more cost-effective compared to the competing solution while providing the potential for increased performance
