HYCCO's Bipolar Plates - Development and manufacturing of key component for tomorrow's high-performance hydrogen fuel cells

Hydrogen is now clearly identified as a cornerstone of the energetic transition. However, limitations on the fuel cell's lifespan are one of the technological locks that impede hydrogen mobility to spread efficiently. HYCCO develops and produces an innovative key component for hydrogen technologies. It brings a major improvement to the green hydrogen ecosystem making it reliable for heavy mobility and many other applications. The solution is an ultra-light, resilient and compact carbon-based bipolar plate for fuel cells. It brings a significant improvement since this component represents 70% of the weight for 30% of the price. It is also suitable for electrolysers - producing hydrogen from (green) electricity - and REDOX flow batteries - a promising low environmental impact energy storage system.
