Ballard’s High Power Density FCmove-XD Fuel Cell Engine

The FCmove^®-XD delivers the highest volumetric power density in the industry for heavy-duty applications, featuring an engine volumetric power density of 0.36 kW/L and gravimetric power density of 0.48 kW/kg. The scalable 120 kW fuel cell engine integrates DC/DC regulated output, enabling up to three modules to operate as one system with a single interface, capable of delivering a combined 360 kW of zero-emission power output.

With a design life of 30,000+ hours of operation – or over one million miles in truck operation at typical duty cycles – the FCmove^®-XD engine is developed to deliver class-leading durability and low total cost of ownership.

Enabled by an innovative “open architecture” design and other new design advances, the powerful and compact FCmove^®-XD enables several important performance improvements (as compared to Ballard’s prior-generation engine), including:

• 120 kW power output from our latest high-performance single stack;
• 33% reduction in total parts count, significantly improving reliability and reducing costs;
• Ultra-high peak system efficiency at >60%, enabling improved fuel consumption (lower total cost of ownership) and efficient heat rejection;
• Wide operating temperature range, up to 95°C;
• Integrated power controller incorporates DC/DC converter, air compressor inverter, and a power distribution unit, along with proprietary software controls, enables improved engine operation and efficiency;
• Rapid up and down transient times, with an innovative hot stand-by mode enabling rapid power increase;
• Improved manufacturability with >50% assembly time reduction;
• Easier access to parts for faster and lower-cost field maintenance;
• Compliance with applicable safety codes and standards;
