Driving forward European fuel cell technology
Read more about driving forward in the GAIA project, which focuses on the development of fuel cell technology.
The GAIA consortium has succeeded in reaching the 1.8 W/cm2 @ 0.6 V power density target set by the FCH 2 JU 2018 Call for Proposals. This leading accomplishment, which hits the FCH 2 JU Multi-Annual Working Plan target for 2024, was achieved with high performance membrane electrode assemblies (MEAs) that integrate new materials and designs developed in the project in a full-size-cell (300 cm2) 4-cell stack, providing a Pt specific power density of 0.25 g Pt/kW.
Advancements on a single-component level were not sufficient to reach the very ambitious target, and significant coordinated progress and synchronised innovation in catalysts, catalyst supports, ionomers, membranes, gas diffusion layers, catalyst layers and MEA design were all essential.
GAIA intends to continue to advance in the remaining 9 months of the contract by now targeting 6,000 operation hours, including at 105 °C, of a 10-cell short-stack. A techno-economic evaluation will then assess how the GAIA MEA cost is positioned with respect to the 6 €/kW MEA cost target of the Call.
