Well maybe, I wonder about the cost efficiencies of multiple fuel cells in modules (usually they're pretty expensive because of the use of costly metals like palladium/platinum). Moving the cell out of the module obviously makes for a dedicated battery truck or dedicated hydrogen truck, but modular automatic liquid fuel let alone hydrogen links I would imagine is hard to keep reliable vs an electrical interface.

So, compared to dedicated hydrogen powered trucks, you'd maybe end up having 110 modules for every 100 trucks, for a modest increase in those costly fuel cells. Maybe the swapping/charging stations could support both kinds and would prefer to give you charged battery modules, but if running behind in the charging, would switch to giving out hydrogen modules. Or maybe only some routes would have hydrogen equipped cargo stations at both endpoints, so the trucks would get different kinds of modules depending on the route - making a gradual rollout of hydrogen fueling infra easy.
