乗用車における燃料電池車の用途を考慮した燃料消費率解析

The fuel consumption rate of passenger cars when the power of internal combustion engine vehicles (ICEVs) is replaced by fuel cells was investigated based on the Worldwide Harmonised Light Vehicle Test Cycles (WLTC) mode, taking into account differences in vehicle applications and vehicle types. The results of the analysis, which took into account maximum vehicle speed and one-fill mileage, showed that in FCVs, the fuel consumption rate of small passenger cars was 1.17 times higher on average than that of regular passenger cars, and among regular passenger cars, the difference was up to 1.41 times higher depending on body type. In addition, the difference in fuel consumption rates among different vehicle types and body types of FCVs narrowed as the driving speed increased, such as when driving on expressways. Therefore, the influence of vehicle type and body type on fuel consumption rate may be relatively small when FCVs are used for inter-city travel compared to when driving in urban areas. Furthermore, the fuel consumption rate of FCVs was found to decrease as the travel speed increases. Therefore, in terms of fuel consumption rate, unlike ICEVs, FCVs should be driven at lower speeds.
