Ballard has launched the FCmove-SC fuel cell module, engineered specifically for use in city buses. With this move, the company aims to align the operating costs of fuel cell powertrains with those of diesel-powered vehicles. “The FCmove-SC is the latest product on Ballard’s new core platform, which addresses the industry’s central challenge: closing the gap in operating costs compared to diesel engines,” says Kevin Colbow, Chief Technology Officer at Ballard.
Technical improvements and increased efficiency
According to Ballard, the FCmove-SC offers several technical enhancements. Volumetric power density has been increased by 25 percent, thanks to the integration of the DC-DC converter within the module. The maximum coolant temperature has been raised from 60 °C to 75 °C, simplifying thermal management in the vehicle. In addition, the number of individual components has been reduced by 40 percent, making maintenance easier.
The module delivers at least 75 kW of power and is designed for stable operation under typical public transport conditions. Its higher thermal tolerance is intended to boost efficiency and make waste heat more usable for interior heating. Ballard specifies an expected service life of around 25,000 operating hours.
By integrating the DC-DC converter and power control into the module, the number of external interfaces is reduced. This is expected to simplify integration into the drivetrain and lower maintenance requirements.
Practical experience and digital services
The FCmove-SC builds on the company’s experience with the previous FCmove-HD module, which has been deployed in over 850 vehicles across Europe. According to Ballard, this fleet has collectively covered almost 100 million kilometres in scheduled service.
The new module can be combined with digital services. Through the FCServiceCloud customer portal, fleet operators can plan preventive and predictive maintenance measures. The goal is to minimise downtime and further reduce operating costs. Ballard will showcase the FCmove-SC in early October at Busworld, Hall 9, Stand 579.
