Abstract
In this paper, the optimal number and the optimal location of on-site hydrogen stations are examined. The hydrogen stations are connected with natural gas pipeline network, and on each station natural gas is reformed into hydrogen, which satisfies the demmand of fuel cell electric vehicles (FCEV). The model is to minimize the sum of two types of cost: 1) facilities construction and operation cost and 2) traveling cost of FCEVs. Assuming the uniform distribution of the demand, the optimal number of the stations is explictly obtained. And a numerical method to obtain the the optimal location of the stations is proposed.
