StoRIES Infrastructures: FZJ PORCES

PORCES of Forschungszentrum Jülich GmbH (FZJ) will provide access to its equipment for the characterization of porous catalyst/ electrode structures. This facility comprises two unique instruments: TAP and nano-CT and further on SEM, XRD und BET equipment.

State of the art: The design of electrochemically and chemically active reactors and electrolysers as components in storage systems demands an intensive knowledge in engineering and chemistry. Corresponding screening experiments, kinetic reactor set-ups and catalyst characterization applying a bundle of experimental hardware will support the development of synthesis catalysts and electrochemically active materials.

Services currently offered by the infrastructure: LCC provides a reactor system for the Temporal Analysis of Products (TAP). This system is able to measure intrinsic kinetic properties of technical catalysts consisting of multicomponent particles. It allows the chemically analysis of intermediates and offers insights in reaction pathways. The Zeiss Versa 420 nano X-ray computer tomograph allows non-destructive imaging of structures and materials in optically non-transparent objects over four size scales, i.e. 500 nm to ~1 mm. This makes it possible e.g. to examine the porous structures of fuel and electrolysis cells ex- and in-situ. Samples up to a maximum size of 10 x 10 x 10 cm can be investigated (depending on x-ray transmission/ absorption).
