A very small electric vehicle, powered with a proton exchange membrane fuel cell operating on reformed methanol, is planned and designed in this paper to solve social problems associated with air pollution and heavy traffic conditions. Next, the driving range is simulated by the experimental data of the output and the performance. The conclusions of this paper are as follows: (1) The power train employing the fuel cell and compact brushless DC motor serves to realize high efficiency and reduce weight for energy saving.

Problems concerning compatibility between commercial vehicles and cars, and aggressiveness of commercial vehicles were taken up extensively throughout the ESV development. Setting our targets on the solution of this problem, improvement of occupant protection and reduction of the damage to goods, we carried out the MSCT (Mitsubishi Safety Concept Truck) research based on our original policy. We fitted up 5 km/h E.A. (energy absorbing) bumper and the E.A. frame in front, and installed the 5 km/h E.A. rear underride guard. For reduction of the damage to goods at collision, we have developed our original E.A. system. Crash tests were conducted with the GVW 7 ton truck and we obtained the following results. 1. Occupant Protection at 30 km/h frontal barrier collision As compared to the standard medium duty truck, the MSCT achieved 75% reduction of cab deformation and 40% reduction of frame deceleration so that it has sufficient survival space. 2.
