ElringKlinger Engineered Plastics develops large-scale cell gaskets in dimensions up to 3,000 mm for electrolysers
Innovative development partner
ElringKlinger Engineered Plastics develops individual, specific sealing designs for different requirement profiles – along the entire hydrogen value chain.
Our processes are geared towards both small quantities and prototypes as well as large quantities. Numerous validated manufacturing processes and our high level of quality and environmental awareness provide all the prerequisites for the implementation of sophisticated solutions and are a central component of our corporate policy, which is reflected in the certifications according to international standards such as IATF 16949, GMP, ISO 14001 and ISO 50001.
Our portfolio includes a wide range of materials and components for PtX-applications – from electrolysis to mobile use. Sustainability and CO2 reduction are at the heart of our solutions for customers.
Maximum performance through individual designs of the sealing components
Our large-scale gaskets for alkaline electrolysis cells are optimally adapted to the individual cell design of our customers and help to increase the performance of the electrolysis stacks.
High efficiency thanks to an application-specific, materialcompatible product design in dimensions up to 3,000 mm.
Individual sealing designs enable good leakage performance, which increases the efficiency of the overall system and improves system safety.
Flexible manufacturing technologies from prototype to series production
Decades of experience with product solutions made of high-performance plastics and thermoplastics, combined with state-of-the-art production technology, enable ElringKlinger Engineered Plastics to flexibly handle customer projects from prototype to series production.
Bipolar plates for electrolysis stacks.
Automated series processes in the areas of metalworking and plastic injection moulding, state-of-the-art joining and coating technology and experience in the production of PEM fuel cell stacks make us the ideal partner for the industrialization of bipolar plates with or without integrated gaskets.
Our subsidiary EKPO Fuel Cell Technologies offers bipolar plates made of corrosion-resistant steel in combination with various coating options, with major advantages in terms of cost-efficiency, power density, and cold-start capability of fuel cells. A functional, high-performance design is developed specifically to meet customer requirements. Production takes place using high-precision, high-volume production-compatible progressive tools in a fully automated, interlinked production process.
How it works: PEMFC stacks consist of alternating stacks of membrane electrode assemblies (MEAs) and bipolar plates. They are interspersed with porous layers that serve to distribute the gas and transfer the electric current. The bipolar plate separates the media and distributes them within the stack. It also ensures uniform cooling of the stack and transfers the electric current to the adjacent cells.
Precise design of our gaskets ensure long service life of the stacks
Our extensive design expertise in the area of beaded screen printing and elastomer gaskets enables us to design the gaskets precisely for our customers' applications and thus achieve the customer's targets for the performance and service life of the PEM electrolysis stacks.
Optimum design and coordination of all product features enables maximum stack functionality.
A good coordination and design of all product features enables maximum functionality of the PEM electrolysis stacks – EKPO Fuel Cell Technologies offers the necessary design know-how.
Fast industrialization of stacks through intelligent integration of sealing materials and bipolar plates
EKPO Fuel Cell Technologies' integrated approach to bipolar plates, specially developed sealing materials and expertise in the field of PEM fuel cells enables our customers to quickly industrialize their electrolysis stacks.
Elastomer/metal-elastomer and plastic-elastomer sealing systems
The right material for every application
Metal-elastomer gaskets are used for highly stressed components such as electrolysis stacks. They consist of a metal carrier with vulcanized elastomer profiles. The elastomer materials used are developed in-house by ElringKlinger and tailored to the respective requirements.
Thanks to state-of-the-art process and injection molding technologies, different materials can be joined to a metal or plastic carrier. Thanks to our many years of experience in plastic injection molding, we can also use this expertise for the production of plastic carriers for plastic elastomer sealing systems. This makes it possible to use the optimum material for every application.
