Improved high-temperature durability

In a conventional fuel cell using a fluorine electrolytic membrane, the materials suddenly soften and deform when the temperature climbs over 80°C, making it inoperable at high temperatures. The aromatic electrolytic membrane used in the Honda FC Stack contains main chains employing a strong, durable aromatic structure that does not soften or deform even at high temperatures. However, even though the aromatic structure displays outstanding anti-deformity characteristics at high temperatures, Honda encountered adhesion problems between it and the electrode layer when using conventional membrane/electrode layer manufacturing processes. To overcome this problem, an original manufacturing process was developed. This resulted in outstanding adhesion between the electrolytic membrane and the electrode layer.
