Toppan Holdings is showcasing new solutions for the hydrogen economy at the Hydrogen Technology World Expo 2025 in Hamburg. The highlight is an ultra-large catalyst-coated membrane (CCM) with a surface area of 3 m², being exhibited for the first time at a trade fair. In addition, a CCM with a surface area of 0.35 m² is being presented. Both products are based on the company’s proprietary double-sided direct coating technology. This technology enables a uniform catalyst layer and flexible membrane shaping.
According to the company, the increased surface area of the CCM can help reduce capital expenditure in hydrogen production, as fewer stacks and auxiliary components are required. The CCMs are designed for use in water electrolysis.
Toppan Holdings is also presenting various membrane electrode assemblies (MEA) for fuel cells. The company offers three standard types that differ in performance, durability, and cost. At the trade fair, five- and seven-layer MEAs with subgaskets and gas diffusion layers (GDL), as well as machined metal samples produced using fine-pattern etching, will be on display. The MEAs are designed for different temperature, humidity, and operating conditions.
Toppan Holdings has been active in the research and development of CCMs and MEAs since 2004. The company draws on its experience in printing technology for the production of these components. The goal is to further establish the products in the European market.
The exhibits will be on display at the booth in Hall B5, Stand 5G15.
