Bipolar plates must have sufficient mechanical and chemical stability and a high electrical conductivity for successful use in fuel cells. ZSW can characterise the properties of bipolar plates comprehensively. Mechanical and electrical characterisation methods are available for this.
The chemical stability of bipolar plates can be studied using both storage tests and electrochemical methods at ZSW. The surface properties – which can be studied by means of optical microscopy, contact angle measurements (drop contour) and the dimensional stability of the bipolar plates (geometric tests and CAD matching) – are also of key importance for use in fuel cells.
