TU Chemnitz and Engel Boost Research on Polymer-based Bipolar Plates for Hydrogen TechnologyTU Chemnitz and Engel Boost Research on Polymer-based Bipolar Plates for Hydrogen Technology

The University of Technology Chemnitz in Germany and Austrian injection molding machine manufacturer Engel are continuing their longstanding partnership in the development of process engineering solutions. In the presence of Dr. Andreas Handschuh, Saxony’s Secretary of State for Science, a duo 450 two-platen injection molding machine was recently handed over to the Institute of Lightweight Structures. This high-performance machine will be utilised for the research and production of bipolar plates made from graphite compounds — a material which, with its high graphite content of up to 80%, presents specific requirements.

Seamless integration with digital environments

The duo 450 is equipped with a specialized injection unit for the production of bipolar plates and a second unit for additional research applications, providing the research team at TU Chemnitz with increased flexibility. Thanks to its advanced interfaces and digital assistance systems, the machine can be seamlessly integrated into digital research and production environments. The energy-efficient drive technology, with powerful servo pump systems, enables resource-efficient manufacturing.

Engel is an international technology partner with a strong focus on developing innovative, customer-centric injection molding solutions and is committed to all areas of injection molding. This includes mobility applications, sealing systems, and the production of bipolar plates for fuel cell and electrolysis applications. Engel promotes the dissemination of expertise through training and educational materials, thereby supporting the integration of digital technologies into injection molding education.

Focus on mobility applications

“Engel is an ideal partner for us, as the company understands our needs precisely, operates with great flexibility, and provides the solutions required for our research on large-area, high-filled polymer bipolar plates,” emphasizes Dr. Jens Emmrich, head of research in polymer technologies and multifunctional lightweight design at TU Chemnitz. “Our joint work on pioneering solutions is a benefit to the entire hydrogen technology sector, where polymer-based bipolar plates can be used in various applications, such as lorries, buses, trains, and stationary energy systems.”

Through this partnership, TU Chemnitz and Engel are building on long-established synergies, contributing to the fundamental development and practical implementation of new applications that are increasingly important in the plastics and hydrogen technology industries.
