General Motors' Hydrotec fuel cell power cubes provide more than 80 kW of quiet, efficient power and can be arrayed 2-3 units per vehicle to achieve higher power ratings.

General Motors said on Wednesday it would supply its Hydrotec fuel cell power cubes to heavy truck maker Navistar for use in its production model fuel cell electric vehicle (FCEV) – the International RHTM Series.

Navistar's FCEV will get energy from two GM Hydrotec fuel cell power cubes.

Each Hydrotec power cube contains 300-plus hydrogen fuel cells along with thermal and power management systems. The power cubes are compact and easy to package and can be used in a wide range of applications, including marine, earth-moving and mining equipment, locomotives and power generators.

Navistar is targeting the fuel-cell-powered semitruck to offer more than 500 miles of range and a hydrogen fueling time of less than 15 minutes.

A pilot for the hydrogen powered semitrucks is planned for the end of 2022, with the first trucks available in 2024. 

The deal with Navistar follows a hydrogen tech deal announced for GM with electric freight truck developer Nikola. Its higher energy density means that hydrogen is seen as a better bet for electric drive HGVs than the lithium-ion batteries used for light duty vehicles.
