Abstract
Introduction of hydrogen energy system using fuel cell is expected because of reduction of the environmental impact, diversification of energy source of supply and decentralization of electronic power supply. However it is necessary for realization of such hydrogen energy system to build the infrastructures of storage and transport of hydrogen demanding huge capital investment and long term. Consequently, the hydrogen energy system which by-product hydrogen from steel mill and oil factory is supply source is focused on. The objective of this study is designing of distributed hydrogen energy system enabling supply fuel cell and fuel cell vehicle with by-product hydrogen. Operation characteristic and economic efficiency of the energy system are estimated by using energy and economic model.
