Johnson Matthey drives world-leading fuel cell performance, increasing power density by 20%


28-07-2021

Johnson Matthey (JM), as part of leading European consortium GAIA, has helped deliver a fuel cell power density of 1.8 W/cm2 @ 0.6V. This represents a 20 per cent increase versus state-of-the-art technology. This market-leading result marks a significant step forward for fuel cell technology and JM’s net zero aspirations.

Working alongside BMW, Freudenberg, 3M and others, JM has been instrumental in delivering this step-change, supplying critical components within the fuel cell stack - the membrane electrode assemblies (MEAs).

This milestone is a further example of how JM is applying its heritage in fuel cell technology to help the world become cleaner and healthier, today and for future generations. The increased power density will lower overall stack cost, in turn helping to advance the commercialisation of fuel cell powered vehicles. This helps with the decarbonisation of the entire transport sector, meaning light duty vehicles such as passenger cars, as well as HGVs and trucks, contribute zero emissions.

It demonstrates how JM will help customers meet the EU's Fit for 55 proposal on 14 July which commits to reduce CO2 emissions in the EU by 55% by 2030, as well as the UK's Decarbonising Transport roadmap, also published on 14 July, which proposes to phase out polluting vehicles weighing between 3.5 tonnes and 26 tonnes from 2035. 

Jo Godden, Managing Director of Johnson Matthey's Fuel Cells business, commented: "Developing a robust fuel cell powertrain solution to decarbonise transportation will be critical to achieving net zero goals around the world. These fuel cell stacks could be powering trucks on our roads in five years' time and will be the best in class fuel cell technology currently available. JM is proud to play a key role in the GAIA project and leverage our extensive fuel cell experience to benefit all." 

The GAIA project, which started in January 2019 and will run for 3.5 years, aims to develop and bring together advanced critical proton exchange membrane (PEM) fuel cell components, integrated into a fuel cell that is capable of delivering the most challenging performance, cost and durability targets required for large-scale automotive fuel cell commercialisation.
