The FCgen-HPS can provide propulsion for light-, medium- and heavy-duty vehicles with volumetric high-power density of 4.3 kilowatts per liter (4.3 kw/l).

"This marks another power density milestone for Ballard over our decades of PEM fuel cell product innovation," said the company.

The FCgen-HPS has a power output of up to 140kW, with scalability to multiple power blocks. It can operate at temperatures as high as 95 degrees celsius, and can start in cold weather temperatures as low as -28 degrees, added Ballard.

Randy MacEwen, Ballard chief executive said, "There is also a growing recognition that zero-emission fuel cell systems are well suited to decarbonize a range of motive applications that have historically been difficult to abate. This is true for buses, commercial trucks, trains, and marine vessels where there is a requirement for heavy payload, extended range and rapid refueling."

The FCgen-HPS was developed by Ballard to meet stringent automotive standards in the company's Technology Solutions program with Audi, and it has signed an agreement with the German carmaker to expand its right to use the stack in all applications.
