Abstract: A single powertrain carrier assembly is provided for mounting or removing multiple fuel cell assemblies in or from an engine bay compartment of a heavy duty truck at the same time. The powertrain carrier assembly can be mounted in new heavy duty trucks, or retrofit into preexisting heavy duty trucks, for example, replacing a diesel engine. The assembly may be provided with a three point mounting system for securing it to a chassis frame, including one front and two angled rear attachment points. In one aspect, the assembly includes a frame structure defining a carrier platform and with lower brackets to secure a first fuel cell assembly below the carrier platform, and upper brackets to secure a second fuel cell assembly above the carrier platform. In another aspect, the assembly includes a frame structure defining lower and upper cavity portions to retain the first and second fuel cell assemblies.
