Process and prototype design

A part of the work carried out at Risø DTU within electrochemical flue gas purification involves preparing the technology for the market, exercises that are necessary for the acceleration of the development. It mainly consists of the following two areas.

Process development

An ongoing effort is made in ceramic processing, with uses traditional forming methods applied on new materials to manufacture the electrochemical cells used for gas purification. The fuel cell and solid state chemistry division at Risø DTU has broad experience within the same forming methods, primarily used in research in fuel cells etc.

A great staff of scientists, engineers, technicians and lab technicians help us understand the many parameters that influence performance and let us control and define the properties of the materials. These are the primary methods investigated: Synthesis, mixing, tape casting, electrophoretic deposition, lamination and sintering.

Proof-of-concept and prototyping

Risø DTU is together with the mechanical department at DTU and Dinex Emission Technology A/S developing novel proof-of-concept models and prototypes to experience the issues that arise when scaling up. These are necessary steps before any ramping up for mass productions is even conceivable.

As a part of an internal scheme to bridge fundamental research, applied technology and the market we are developing a small proof-of-concept component that will be able to clean a part stream of a diesel engine. This task is vital before a prototype can be developed for a "full scale" test, where a component can clean the entire exhaust stream from a commercially available engine.
