Bramble energy


The only fuel cell company with Gigafactories



Founded in 2016 at University College London (UCL) and Imperial College London, Bramble Energy Ltd., through revolutionary fuel cell design and manufacturing techniques have developed the unique, patent protected, printed circuit board (PCB) fuel cell – the PCBFC™.

The PCBFC™ utilises cost-effective production methods and materials from the PCB industry to reduce the cost and complexity of manufacturing of proton exchange membrane fuel cells (PEMFCs).

Bramble Energy’s ability to leverage the global high-volume PCB industry means that we are the first fuel cell company with the manufacturing capacity to supply gigawatts of fuel cell hardware, something the battery industry has spent many years and £B’s to achieve.

The hydrogen fuelled PCBFC™ combines a number of patent protected innovative features including a unique lightweight PCB construction, optimised internal flow field design and an advanced electrode anti-corrosion passivation layer.


The PCBFC™ is highly versatile with its light weight, adaptable form factor and low cost making it the ideal choice for all polymer electrolyte membrane fuel cell applications. Individual modules can be manufactured to suit specific design and space requirements and modules can be stacked to provide a range of power outputs.


Low cost

Well-established PCB fabrication techniques allows for rapid adaptation and manufacture of PCBFC™ modules, whilst keeping construction costs low. The PCBFC’s™ unique manufacturing route also makes it amenable to low volume production requirements which allows for significant cost reduction for higher volumes.


Bramble Energy’s unique patent protected fuel cell manufacturing route allows us to contract manufacture our fuel cells at almost any printed circuit board (PCB) factory in the world. This means we are the only fuel cell manufacturer capable of supplying gigawatts of fuel cell hardware at any given time, a feat the battery industry has spent and is spending $Bn’s to achieve.


Using a laminated construction method, the PCBFC™ is physically robust and shock-resistant. Our proprietary metal passivation technology inhibits chemical degradation allowing long operating lifespans; demonstrated through long-term prototype testing with extensive mechanical strain tests that have exceeded industry standards.
