Ionotec carries out research on the fabrication of ion-conductive and electron-conductive coatings for electrode development with various applications in electrochemistry:
Some applications require the development of novel electrodes designed to operate at high temperatures. Coatings can be made either fully dense or intentionally porous, and multiple coatings are feasible as shown in this electrode assembly used in fuel cells and other electrochemical systems.
Ceramic coatings such as zirconium oxide on metal foil can be made either electrically insulating or electrically conductive by doping treatments, incorporation of a metallic component, and appropriate firing treatments. The coating may be deposited or grown in-situ by chemical reaction depending on the materials involved. Coating thickness can be controlled accurately.
Other applications involve conventional electrodes which are surface treated in order to limit corrosion and to provide stable performance in electrolysis. Identifying cost-effective alternatives to conventional noble-metal based electrodes is becoming increasingly important without loss of the characteristics important to successful electrode operation:
Solving such problems demands considerable expertise in materials chemistry, which is one of Ionotec’s strengths. Please contact us to discuss your application in complete confidence.
