Possibility of fuel cell fast charger and its arrangement problem for the infrastructure of electric vehicles

Fuel cell is a very promising energy production system to supply electricity and heat with high efficiency and low impact to the environment. Presently, the effort is paid both to applications for dispersed generator and automobile energy source. However, the infrastructure for fueling of pure hydrogen has been still discussing and investigating. In this paper, the authors propose a new concept for constructing the infrastructure of EV by fuel cell chargers. This unique application is simulated by the scenario analysis as an arrangement problem. The approach uses the modified weighted Voronoi Diagram providing a proper allocation of the chargers for electric vehicle (EV). The simulation presents a suitable distribution and the possible implementation number of EVs when 100 chargers, including the fast charger and the parking charger, are introduced in Tokyo metropolitan area.
