Electronics printing solutions provider Toppan has installed production equipment for Catalyst Coated Membrane (CCM)/Membrane Electrode Assemblies (MEA) at its Kochi plant to mass produce sheet-type CCM/MEAs.
The newly installed equipment uses a proprietary manufacturing method, allowing direct coating of both sides of the electrolyte membrane, resulting in mass production of high-performance, high-output CCM/MEAs, essential components for hydrogen production, storage, transportation, and fuel cells.
The addition of a proprietary material enhances CCM/MEA durability by controlling the porosity of catalyst layers and adjusting the degree of ease with which water generated by hydrogen use can be discharged, as water accumulation causes degradation of the carbon and catalyst metal in the catalyst layer. This improves the overall performance, particularly in fuel-cell vehicles where suppression of electrode degradation can help extend overall travelling distance.
Jin Endo, managing executive officer of R&D strategy and business development at Toppan, outlined the company’s plans. “Going forward, we will scale up and bolster equipment in step with the growth of the business as we ensure a stable supply of CCM/MEAs for every application to help drive the creation of a hydrogen-based society,” he said.
The company currently offers customisation options for CCM/MEAs, with a basic lineup and the ability to tailor solutions to individual user needs.
Established in 1900, Toppan is a global provider known for sustainable solutions across various sectors, including printing, security, packaging, electronics, and digital transformation. The company employs over 50,000 individuals and focuses on shared sustainability goals. Its Kochi plant is certified for quality control and implements comprehensive processes for manufacturing thin-film-transistor liquid-crystal displays (TFT LCDs) for automobiles.
