AVL is partnering with Red Bull Advanced Technologies, a division of the Red Bull Racing Group. The aim of the partnership is to develop a new generation of fuel cells with ultra-high power density. The lightweight design is expected to be two-thirds lighter than conventional fuel cell systems. This is intended to make them a trailblazer for net-zero emissions in the automotive, motorsport and aviation industries.

The cooperation combines the development service provider's portfolio in the area of PEM fuel cell technology with Red Bull's expertise in lightweight construction, design and aerodynamics. Jürgen Rechberger, Head of Hydrogen & Fuel Cell at AVL, hopes that by pooling knowledge and experience, the gravimetric power density of fuel cell technology can be increased by a factor of three.

Fuel cell with the highest power density to date

This is expected to surpass all systems currently available worldwide. As AVL reports, joint studies show that improvements in gravimetric power density are achievable: The forecasted values are 6 kW/kg at the stack level and 2 kW/kg at the system level.

The targeted system is an important milestone for both companies on the path towards climate-neutral mobility. Sectors such as aviation, future motorsport series, and a wide range of other applications with maximum payload are thus expected to achieve the power density dimensions required for hydrogen mobility.
