For mobility, current power can track and excess energy is stored to save. Since the fuel cell power is determined by the fuel velocity, but the fuel cell cannot produce the maximum power at will, then battery power is required. If less energy is required, there will inevitably be losses and the energy is stored in lithium batteries.

Introduction Why are lithium-ion batteries used more in the civilian sector, while fuel cells are used more in the military sector? For mobility, current power can track and excess energy is stored to save.
