High-performance fuel cell engine for heavy-duty vehicles

Ballard Power Systems’ 9th generation, high-performance fuel cell engine, the FCmove-XD delivers a high volumetric power density for heavy-duty applications, and features an engine volumetric power density of 0.36kW/L and gravimetric power density of 0.48kW/kg. The scalable 120kW 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 360kW 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 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 including 33% reduction in total parts count, significantly improving reliability and reducing costs; high peak system efficiency at >60%, enabling improved fuel consumption and efficient heat rejection; wide operating temperature range, up to 203°F (95°C); integrated power controller incorporates DC/DC converter, air compressor inverter, and a power distribution unit, along with 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; easy access to parts for fast and low-cost field maintenance; and compliance with applicable safety codes and standards.
