MAHLE Powertrain and Bramble Energy have jointly agreed to continue their collaboration to develop Bramble’s PCBFC hydrogen fuel cell technology. The phase 1 demonstrator vehicle was launched at the Cenex Low Carbon Vehicle show. Bramble Energy’s innovative PCBFC technology significantly reduces the manufacturing cost of hydrogen fuel cell powertrains. While conventional fuel cell stacks rely on stamped plates to hold the various layers, Bramble Energy’s approach leverages PCB manufacturing technology, which can be produced cheaply, in virtually any shape using flexible production techniques.MAHLE Powertrain was chosen as the project’s integration partner due to its decade-long experience in powertrain technology integration and its expertise in EV control systems and thermal management. Its recent Memorandum of Understanding with Bramble strengthens the duo’s relationship ahead of the development of the phase 2 demonstrator.The phase 1 results of the collaboration are based around a Renault Kangoo ZE delivery vehicle that sees a 5 kW Bramble Energy fuel cell integrated into the powertrain acting as a range extender. Future development will focus on creating a derivative with a higher power output and increased overall efficiency.Hydrogen fuel cells generate electricity using an electromechanical reaction rather than the combustion of a traditional engine. This not only eliminates harmful emissions but is silent in operation with no moving parts and produces only heat and water as by-products.
