Cummins unveiled its fourth-generation hydrogen fuel cell engine at the IAA Transportation Show.
The fuel cell technology comes in single 135 kW modules and dual 270 kW modules that are tailored to the duty-cycle, performance, and packaging needs of medium- and heavy-duty vehicles and buses.
Two major truck manufacturers, Scania of Europe and Daimler Trucks of North America, have already established partnerships with Cummins to build and install these next-generation fuel cell engines in prototype vehicles. Integrating the systems into automobiles is simplified by the use of fourth-generation variable pressure technology, which also increases power density, power nodes, and operating temperatures. Both the working cycle economy and the durability are high, leading to a low lifetime cost.
