Eidgenössische Materialprüfungs- und Forschungsanstalt, Dübendorf, Switzerland (Empa)

Profile

Empa is a fully independent public research institution with about 800 employees, concentrating on the five strategic R+D programmes Nanotechnology, Adaptive Materials and Systems, Technosphere& Atmosphere, Healthy Human and Materials for Energy Technologies. The Laboratory 138, “Hydrogen & Energy” at Empa, addresses scientific questions and technological problems from hydrogen synthesis, hydrogen in solids to hydrogen as an energy carrier as well as applications like catalytic combustion of hydrogen, batteries and supercaps.

Empa’s experience ranges from hydrogen sorption in metals, hydrogen in metallic nano-clusters, crystal structure analysis of complex hydrides, hydrogen adsorption on carbonous nanostructures, and electrochemical hydrogen sorption in intermetallic compounds to p-element complex hydrides. We develop instruments for the specific investigation of hydrides, e.g. PCT-apparatus, and sensors, and we have demonstrated several solid hydrogen storage systems.

The search for practical hydrogen storage materials is accompanied by the investigation of model systems, in particular hydride thin films. During the past 10 years, EMPA has been involved in the development and characterisation of advanced ceramic components for SOFCs and SOECs in National and European projects. The competences cover the synthesis of specific perovskites, ceramic processing for cell production and advanced characterisation techniques. Empa is a member of the New European Research Grouping on Fuel Cells and Hydrogen, N.ERGHY.

In BOR4STORE Empa will focus on materials preparation (WP1), scale-up and cost effective synthesis (WP4), on thermodynamic, kinetic and structural characterization (WP1), with particular focus on gas sorption analysis.
