High Power Density Automotive Membrane Electrode Assemblies
Abstract
<jats:p>The European GAIA project focussed on the development of novel ionomer, membrane, reinforcement, catalyst, catalyst support, gas diffusion and microporous layers, and layer constructions for high power density, high current density automotive membrane electrode assemblies (MEAs). Reaching a sufficiently low degradation rate (11-14 µV/h in an automotive drive cycle including operation at 105 °C) consistent with the 6,000 hour lifetime target while also succeeding in achieving the 1.8 W/cm<jats:sup>2</jats:sup> power density at high current density (3 A/cm<jats:sup>2</jats:sup>) target was a major challenge, and the outcomes of GAIA represent an important step forward for fuel cell transport MEA technology. The results are all the more important that they were obtained with MEAs using materials developed and up-scaled in GAIA. By reaching this high-power density without increasing platinum loading, the Pt-specific power density was reduced to 0.25 g Pt/kW. Costs analysis demonstrated that recycling (catalyst and ionomer) has the potential to significantly reduce MEA cost, and that, with this, the cost per kW of the high power density GAIA MEAs approaches the 6 €/kW target. This presentation will outline the main materials development steps, summarise testing protocols and the results of automotive size cell short stack tests.</jats:p><jats:p><jats:italic>Acknowledgement.</jats:italic> This project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (now Clean Hydrogen Partnership) under grant agreement n°826097.
