Parker Hannifin's Prädifa Technology Division has developed an array of sealing solutions tailored to meet the unique demands of electrolyzers and fuel cells, particularly focusing on the critical role of bipolar plates within the systems. These sealing solutions play a vital role in ensuring the efficiency and safety of hydrogen technology applications. Electrolyzers and fuel cells are integral to the sustainable production and utilization of hydrogen, sharing similarities in their technology composition and functional principles. The stack, including components like the membrane electrode assembly (MEA) and the crucial bipolar plates, plays a central role in these systems. Bipolar plates not only connect individual cells but also facilitate the transportation of gases and liquids while sealing the stack against external factors. Inadequate sealing can lead to performance issues or safety concerns. Parker's sealing solutions aim to address these challenges by offering a range of products, from rubber frame seals for cost efficiency to PTFE seals for high chemical resistance. These solutions are designed to withstand the harsh operating conditions of fuel cells and electrolyzers, ensuring the longevity and safety of the systems. By providing diverse sealing options in various sizes and shapes, Parker Prädifa enables efficient mass production and reliable operation of hydrogen technology systems.
