Porous Organic Cages for CO2 Capture and Confined Reduction

Angewandte Chemie, EarlyView.
Porous organic cages (POCs) enable the coupling of CO2 capture and conversion through the interplay of molecular structure and solid‐state organization. Beyond intrinsic cavities, packing‐dependent pore accessibility and mass transport govern local CO2 concentration and catalytic performance, linking adsorption to reactivity in integrated capture ...

Numerical simulation of Effect of Contact Pressure on Mechanical Behavior of Gas Diffusion Layers (GDL) and PFSA Membrane Assembly

Mediterranean Journal of Chemistry, 2019
In this study, a Finite Element model has been implemented based on numerical modelling simulations to predict the mechanical behaviour of a representative unit of the fuel cell stack. The GDL deformation has been modelled as a combination of elastic deformation and fibres slippage.
