Symbio unveiled its new StackPack 75 75-kW optimized fuel cell system tailored for intensive mobility. With its 75-kW power output, the StackPack 75 fuel cell system is specially designed for heavy-duty use in urban and intercity buses and coaches, light and medium trucks, as well as off-road handling and construction equipment.

StackPack 75 offers:

• Best-in-class compactness: with a volume of 268L and a mass of 200kg, it underpins maximum payload, range and ease of integration.

• High operating temperature (85°C) improving heat dissipation efficiency and reducing cooling capacity requirements. As a result, the size of the cooling system and its fan power are also reduced, facilitating vehicle integration and saving energy.

• Extensive modularity to meet all technical and operational specifications including the possibility of combining two or more StackPack in a single vehicle to deliver requested power output.

Symbio technology is designed to deliver the best performance/competitiveness ratio over ten critical performance dimensions. That holistic performance approach enables to define the best solution for each application, optimizing total cost of ownership throughout the vehicle lifecycle, achieving optimal performance without oversizing.

Symbio’s new StackPack 75 is ready for large-scale production at Symbio’s SymphonHy gigafactory, the largest site dedicated to the development and production of hydrogen fuel cells in Europe. SymphonHy and the development of the StackPack 75 technology have been supported by France Relance / France 2030 through the Hy2Tech Important Project of Common European Interest (IPCEI) hydrogen program, aiming to foster the development of high-performance and competitive solutions to promote sustainable and efficient zero-emission mobility.
