"Batteries are great for storing energy but need to be charged rapidly.
The fuel cell can deliver large amounts of power very quickly."
This is a misunderstanding, the reason the batteries exist between the fuel cell and the vehicles are because it allows; charging vehicles at greater rate than the attached fuel cell could provide, managing the variable power draw of vehicles charging profiles without needing to scale up and down the fuel cell output, letting you run the fuel cell continuously at it's peak efficiency.
New EVs can charge at tremendous rates now, a 50kW 10ft container fuel cell would be underpowered for even one vehicle, but if it's continuously charging a huge battery then the system as a whole can charge two or more vehicles easily.
