Projektbeschreibung
Ein stabiler, kostengünstiger Katalysator für die Wasserstoffproduktion durch Wasserspaltung
Wasserstoff wird in einer CO2-armen Zukunft eine Schlüsselrolle spielen. Er kann nachhaltig hergestellt werden, indem erneuerbare Energiequellen wie Sonnenenergie zur Spaltung von Wassermolekülen verwendet werden. Protonenaustauschmembran-Elektrolyseure sind eine ausgereifte Technologie, deren Einsatz jedoch aufgrund des Mangels an stabilen, kostengünstigen Katalysatoren, die Nichtedelmetalle enthalten, zurückgehalten wird. Ein ehemaliges EU-finanziertes Projekt, PhotocatH2ode, untersuchte eine Koordinationspolymerstruktur für amorphes Molybdänsulfid. Das Projekt verfeinerte das Verständnis seines katalytischen Mechanismus und entwickelte Strategien zur Behebung reduktiver Korrosionsprobleme, welche die Umsetzung dieses erdreichen Wasserstoffentwicklungskatalysators in Protonenaustauschmembran-Elektrolyseuren bisher eingeschränkt haben. Das Projekt PRODUCE-H2 wurde ins Leben gerufen, um die Formulierung dieses Katalysators zu optimieren und ihn in Polymermembranen zusammenzubauen, seine Leistung zu bewerten und seine Produktion zu verbessern.
Ziel
Hydrogen (H2) generated from renewable energies, such as solar and wind, and water has a huge potential as a carbon-free energy vector which can be exploited on demand through fuel cell technologies. Proton-exchange membrane electrolysers (PEMEL) are a mature technology that can be coupled with intermittent renewable power sources. However their wide deployment still depends on innovative breakthroughs regarding the design of alternative catalysts avoiding the use of precious metals and fulfilling three main characteristics: sustainability, cost-effectiveness and stability.
In the “PhotocatH2ode” ERC Frontier Research Starting Grant (consolidator stream), we explored a coordination polymer structure for amorphous molybdenum sulfide (a-MoSx), refined the understanding of its catalytic mechanism (Artero and coll., Nature material 2016) and developed strategies to remedy reductive corrosion issues that so far limited the implementation of such earth-abundant H2 evolution catalysts in PEMEL. We aim at exploiting these new findings in PRODUCE-H2, an ERC Proof of Concept project which proposes to (1) optimize the formulation of these catalytic materials and assemble them in polymer-membranes, (2) assessing their performance and quantifying their stability during long-term tests performed under realistic operating conditions, (3) upscaling their production thanks to a newly developed synthetic process and (4) implementing them in a noble-metal-free PEMEL prototype. PRODUCE-H2 will exploit pre-existing and newly created intellectual property with the aim of proposing a cost-effective industrial solution for PV-coupled on-site hydrogen production. This project will be in close collaboration with Toyota Motor Europe who have been selling fuel cell cars since 2015.
