H20: 20 W PCBFC system

This Bramble Energy PCBFC is a 20 W, air cooled, hydrogen fuel cell suitable for many small projects and uses.


The 20 W hydrogen PEM (proton exchange membrane) fuel cell generator is capable of delivering 20 W of DC electrical power for off-grid and backup power applications. It is ideal for supplying power to continuous loads running on 12V or 24V rechargeable batteries. Typical applications include remote monitoring and lighting systems or security cameras. The system is fuelled with readily available industrial hydrogen.
