"Up to now, much work has been performed on the catalyst but much on the active layers’ structure and on the two other major components (carbon and electrolyte) whereas they do have a major impact on the MEA’s performance and on Pt utilization.Based on this analysis, PEMICAN proposes to reduce the Pt loading for automotive application down to 0.15 gram of Pt per kW, by a twofold approach:1.to increase Pt utilization and power density by improving effective transport properties of ALs by tuning some properties of the electrolyte and by adding special carbon blacks in order to improve catalyst, electrolyte distribution and water management;2.to reduce Pt loading by controlling its distribution: very thin layer on the anode side and gradients of Pt on the cathode side. These structured layers will be defined in order to optimise the utilization of the Pt.The combination of these two approaches will allow reducing the total mass of Pt for a given power density.Whereas the main objective of PEMICAN is to develop and manufacture MEAs with reduced quantity of Pt, it is supported by numerical modelling to help defining the best Pt distribution. Special structural and electrochemical characterizations will be done to improve the existing models and to analyse the performance of our MEAs as a function of manufacturing processes and properties of components. Performance and durability tests under automotive conditions will be performed and analysed.PEMICAN will demonstrate gains in terms of Pt cost (g Pt/kW) obtained by improving the design and properties of the ALs. Its results will be useful also In the future when non pure Pt is available.The Consortium is built-up on the expertises of 6 European organisations with complementary skills: 2 Research Institutes (CEA and INASMET), 1 University (IMPERIAL COLLEGE), 2 industrial suppliers (SOLEXIS, TIMCAL) and 1 automotive OEM (OPEL). Among these partners, 4 of them are active members of the FCH JTI."
