Freudenberg supplies gas diffusion layers for fuel cell stacks

Freudenberg Performance Materials (Freudenberg) has concluded a high-volume, multi-year contract with a global automotive tier one supplier to supply high-performance gas diffusion layers for the stacks forming the core of the fuel cell systems produced by the leading automotive supplier. Global target applications are mid-sized and heavy commercial vehicles as well as buses. Freudenberg is supporting the customer’s global fuel cell activities, thereby also accelerating the breakthrough of mass-produced fuel cell stacks.

Fuel cell technology is an important element of a successful energy transition. Gas diffusion layers play a key role in this context: they are indispensable for the functioning of a fuel cell and have a significant impact on the performance of a fuel cell stack.

Fuel cell technology is an important element of a successful energy transition. Gas diffusion layers play a key role in this context: they are indispensable for the functioning of a fuel cell and have a significant impact on the performance of a fuel cell stack.

A fuel cell converts the chemical energy of hydrogen and atmospheric oxygen into electricity. Functionally-optimized gas diffusion layers made of carbon-fiber based nonwoven are installed on both sides of a catalyst-coated membrane positioned in the middle of the fuel cell. The gas diffusion layers distribute hydrogen and oxygen evenly to the membrane and remove the electricity, heat and water generated by the CO2-free chemical reaction. They also protect the sensitive membrane and are optimized to suit the bipolar plate. A fuel cell stack is made up of several individual fuel cells.

Freudenberg already has more than 20 years of unique expertise in the development and production of gas diffusion layers for fuel cell applications in the mobility sector and for porous transport layers used in electrolyzers. Freudenberg is currently expanding its production capacity at its Weinheim headquarters by installing additional lines. Further investments are on the verge of implementation.

Freudenberg hosts German National Hydrogen Council meeting

Freudenberg Performance Materials – the Freudenberg Group’s nonwovens specialist – was hosting a meeting of the German National Hydrogen Council at the Freudenberg headquarters in Weinheim, Germany, on September 16. As a leading global supplier of technical textiles, Freudenberg Performance Materials provides fuel cell components for mobility applications and for electrolyzers used to produce CO2-free hydrogen.

Freudenberg Performance Materials – the Freudenberg Group’s nonwovens specialist – was hosting a meeting of the German National Hydrogen Council at the Freudenberg headquarters in Weinheim, Germany, on September 16. As a leading global supplier of technical textiles, Freudenberg Performance Materials provides fuel cell components for mobility applications and for electrolyzers used to produce CO2-free hydrogen.

The German National Hydrogen Council was appointed by the German government and acts as an independent, non-partisan advisory board. The council board currently consists of 25 high-ranking experts in the fields of economy, science and civil society. The objective is to assist and advise the State Secretaries’ Committee on Hydrogen in the further development and implementation of Germany’s National Hydrogen Strategy. Council meetings are hosted by one of the board members to enable the council to deepen its knowledge of the relevant technologies, value chain roles and challenges. Dr. Silke Wagener is a member of the council board, and represents the Freudenberg technology group, giving input on suppliers’ know-how as well as contributing her decades-long expertise in technological solutions for the hydrogen industry.

During a tour of the factory organized for the council board members, Freudenberg Performance Materials explained the development and production of performance-critical gas diffusion layers manufactured from carbon fiber-based nonwovens for fuel cells and porous transport layers for electrolyzers. The tour highlighted the potential for improvements from a supplier’s perspective, such as the need for very timely exchange and collaboration along the value chain. Functioning, unbroken and scalable value chains, in parallel with the development and scaling of hydrogen infrastructure, are key prerequisites for the hydrogen industry to fulfill its vital role in the transformation to climate neutrality.

Gas diffusion layers are one of the main components at the heart of the fuel cell. Their function is to transport gases and liquids in the cells. They have a significant impact on system performance and costs, and are indispensable for the functioning of fuel cells. The same applies for porous transport layers that are the key component of electrolyzers for the CO2-free production of what is called green hydrogen.

Fuel cells in combination with green hydrogen are an important technology for CO2-free mobility, in particular with reference to buses, heavy-duty trucks and trains. Other uses include stationary applications such as stationary power generation or heat generation in buildings or industry.
Apart from mobility, green hydrogen also plays a key role in climate-neutral energy supplies in the industrial sector, particularly in the chemical and steel industries.

SGL Carbon awarded by Hyundai as Supplier of the Year 2019

Automatized quality control of gas diffusion layers for fuel cells at SGL Carbon in Meitingen

  • One of only two awarded overseas suppliers
  • Long-term cooperation for a substantial production ramp-up

Mid of January SGL Carbon received the “Supplier of the Year 2019” award for excellence in quality management and contributions to strengthen the overall competitiveness of Hyundai Motor Group related to the manufacturing and supply of fuel cell components. The award is being granted by the Korean automaker once a year, evaluating several hundreds of suppliers from across the world in different categories. This time only two overseas suppliers have been awarded.

SGL Carbon and the Hyundai Motor Group have been cooperating on fuel cell technology for almost 20 years. Last year, the two companies agreed on an early extension to the existing supply agreement for SIGRACET® gas diffusion layers for the NEXO fuel cell car, encompassing a new long-term cooperation including a substantial ramp-up of the current production and supply volumes.
