Title: Teja Roch: Innovator in Fuel Cell Technology
Introduction
Teja Roch is a prominent inventor based in Dresden, Germany. She has made significant contributions to the field of fuel cell technology, holding a total of 4 patents. Her innovative methods and designs have the potential to enhance the efficiency and performance of electrochemical cells.
Latest Patents
One of her latest patents is a method for producing bipolar plates for fuel cells. This method involves guiding one or two metal strips through a series of devices. The second device is designed for fine cleaning and/or nitriding of the metal strip, while the third device applies a surface coating that improves adhesion. A carbon layer is applied in a fourth device. The metal strips are then shaped to form channels, and the shaped strips are positioned to allow for laser beam joining. This continuous process ensures high efficiency in the production of bipolar plates.
Another notable patent is the bipolar plate designed for electrochemical cells, particularly for proton-exchange membrane (PEM) fuel cells. This invention features a metallic substrate with a carbon-based layer that reduces electrical contact resistance. The layer is primarily sp2-bonded and has a carbon fraction ranging from 50% to 100%. The substrate may also include a surface region modified by nitriding and/or carburizing, enhancing its performance within the electrochemical cell.
