Test methods to measure fuel economy in direct hydrogen fuel cell vehicles

摘要

The development of fuel cell vehicles and their demonstration on the road are actively conducted in recent years, but test methods for fuel economy are not yet to be established. The purpose of this study is to standardize simple and accurate methods. For study purposes, the following test methods are proposed: the electric current method, pressure method and weight method. This paper deals with the possibility for application and related issues for each of these test methods.
