A new fuel cell system that claims to address major electrification challenges in the HGV and bus markets, including range and refuelling times, has been launched.
Engineered by propulsion systems specialist Drive System Design (DSD) the fuel cell’s multi-input, multi-output converter is capable of delivering 300kW of power, surpassing previous limits of 150kW.
DSD said its breakthrough couples multiple fuel cell systems, unlocking the high-power outputs required for heavy-duty vehicle applications.
It added that unlike conventional systems that require individual converters for each fuel cell stack, DSD’s solution streamlines the process with a single, integrated converter.
This eliminates the need for multiple high- and low-voltage supplies, reducing complexity, cost and packaging size.
Intelligent Energy led the development of the IE-DRIVE HD fuel cell system and to support safe and reliable operation, General Engine Management Systems (GEMS) delivered an ISO 26262-compliant electronic control unit, ensuring robust system control in line with automotive safety requirements.
James McGeachie, head of electrified powertrain at DSD, said: “Our first-of-its-kind converter will give the heavy-duty vehicle industry a welcome power boost to drive it forward on its electrification journey.
“Working closely with GEMS and Intelligent Energy has been key to this success. Each partner has brought sector-leading experience, expertise and innovation to the programme, delivering a world-class fuel cell system solution.”
Dr Ashley Kells, programme director at Intelligent Energy, added: “With simplified vehicle integration, a longer life and being certification ready, the IE DRIVE HD fuel cell is now even better positioned to provide a zero emissions solution for heavy duty applications.”
