ProtOMem in the context of the "Energiewende"

Within the framework of the "Energiewende", two aspects are of prime importance: improving the efficiency of energy conversion processes, and decreasing greenhouse gas emissions from electricity generation, i.e. capturing CO2 and/or moving towards hydrogen-based systems. Permeation membranes (for H2 or O2 production and separation) and fuel cells (for efficient electricity generation) play an important role in this context.

Focus Protomem


Both types of devices require gas-tight membranes exhibiting selective transport properties (exclusively ion transport -> electrolytes for fuel cells, neutral component transport -> permeation membranes) as key functional materials. Their functioning depends critically on intrinsic materials properties (ionic and/or electronic conductivity, catalytic activity, chemical and mechanical stability), as well as on the ability to manufacture a suitable microstructure (gas-tight membranes 5-20 µm thick, on porous supports giving mechanical stability but allowing for gas diffusion). Such membranes must be fabricated with sufficiently large areas (e.g. 10 X 10 cm2), close to the final application size in fuel cells and membrane reactors and at acceptable cost.

ProtOMem will bridge the gap between ceramic lab scale samples and large-area supported membranes to bring materials with optimized structural and functional properties from lab scale into actual application ("enabling technology"). This is based on close interplay of fundamental scientific insight into the material's bulk and grain boundary properties, and of the membrane fabrication process development.
