I'm excited to share that our latest research paper has been published today in the Journal of the Electrochemical Society! ECS - The Electrochemical Society🎉 The full paper can be found here: https://lnkd.in/d_gzqDAg In our study, we investigated the impact of carbon support design and pore morphology on the performance and longevity of proton exchange membrane fuel cells. Here are some important discoveries: - Durability vs. performance trade-off: Porous carbon supports show a ~5-fold improvement in Pt surface area retention compared to solid carbons due to the protective effect of internal pores, though they suffer from oxygen transport limitations and thus performance at high current densities. - Optimized performance and durability with accessible pores: Catalysts with accessible porous carbon supports strike a balance, preserving durability (~3-4-fold improvement in ECSA retention over solid carbon) while optimizing performance at all current densities, attributed to better oxygen transport that boosts high current density performance. - Performance evolution for porous carbons: Over 200,000 voltage cycles, we monitored changes in catalyst accessibility and performance. The initial performance boost in porous carbon is likely due to oxidative pore opening from repeated low-potential operation. Conversely, the rise in dry Pt utilization especially after extensive aging tests can be attributed to the continuous migration of Pt particles to the external carbon surface. A special thanks to my co-authors Timon Lazaridis and Hubert Gasteiger for their great collaboration and invaluable contributions. #PEMFC #Electrochemistry #Sustainability #CleanEnergy

Excited to share our recent collaboration with Polytechnique Montréal (Professor Clara Santato and Molood Hoseinizadeh). In this work, we introduce the first use of our MWCNT produced from our patented technology: natural gas photo reforming at ambient conditions as multifunctional conductive additives. By adding oxygen surface functionalized MWCNT (O-MWCNT) to biosourced, redox-active Sepia melanin, we have established a novel pseudocapacitive electrode material through a one-pot water ultrasonication process, without the use of any surfactant or organic/inorganic binder. These O-MWCNTs have been instrumental in facilitating (i) the formation of efficient conductive pathways between Sepia granules and (ii) enhancing the efficiency of electronic coupling between the ultrasound-treated carbon cloth and the Sepia melanin granules. The MWCNT:Sepia-based semi-solid-state symmetric supercapacitors exhibit a high capacitance of up to 118 F g−1 at 0.5 A g−1. Furthermore, these devices offer a high energy density of 18 Wh kg−1, a power density of up to 221 W kg−1, and demonstrate remarkable cycling stability with 100% capacitance retention and Coulombic efficiency after 10,000 cycles. Additionally, the supercapacitors consistently perform well when subjected to mechanical bending at various angles. https://lnkd.in/gy9MN-Vt

I am thrilled to announce the publication of our recent scientific paper in RSC Energy Advances! Glad to say that this is the second first-author publication this month. 🎉 Our research focuses on the utilization of electrospun composite nanofibers for high-energy-density hybrid supercapacitor electrodes. Our study explores the utilization of electrospun composite nanofibers for the fabrication of high-performance supercapacitor electrodes. Electrospinning various compositions followed by carbonization and activation with CO2 yielded C/Cu/Cu2O nanocomposite fibers. These fibers exhibited a specific capacitance of 253.4 F/g at 1 A/g current density in a 6 M KOH electrolyte.
