OBJECTIVES

GAIA aims to developing a high performance automotive MEA that provides the materials and designs that satisfy the cost target by providing high power density at high current density, while also attaining the other essential objectives of durability, reliability and high operation temperature. Its intention is to:

    • Realise the potential of these components in next generation MEAs showing a step-change in performance that will largely surpass the state of the art by delivering a beginning of life power density of 1.8 W/cm2 at 0.6 V;
    • Validate the MEA performance and durability in full size cell short stacks, with durability tests of 1,000 h with extrapolation to 6,000 h.
    • Provide a cost assessment study that demonstrates that the MEAs can achieve the cost target of 6 €/kW for an annual production rate of 1 million square metres.

GAIA will develop and bring together advanced critical PEM fuel cell components. These components will be integrated into a fuel cell that is capable of delivering on the most challenging of the performance, cost and durability targets required for large-scale automotive fuel cell commercialisation. New designs, architectures, constructions and deposition methods will be used at the level of the components and at the level of their integration in the catalyst layer, where novel constructions and coating methods will be used. While some of the materials and components are early developments with the technology concept formulated, the majority have already been proven experimentally. These components will be further advanced, optimised and integrated into next generation automotive MEAs to demonstrate the application of the technology.
