The new fuel cell technology will leverage Eaton’s Twin Vortices Series (TVS) technology to improve fuel efficiency. Eaton will leverage its corporate research labs in Golden, Colorado, and Additive Manufacturing Center of Excellence in Southfield, Michigan, to produce the technology, using power electronics and 3D printing. Eaton says its vehicle group will design and test a sub-scale, proof-of-concept system prototype utilizing its TVS technology that delivers a significant reduction in air system power consumption and fuel cell efficiency for heavy-duty truck applications.

Eaton says its TVS technology is ideal for harsh environments, as it can tolerate water, has operating maps with broad efficiency, and provides accurate airflow control in proportion to speed. These properties enable a water applicator to replace the humidifier to achieve higher operating pressure ratios and isentropic efficiencies.
