Abstract
Hydrogen that has multilateral functions as for energy performance is a possible energy carrier for the future. This paper deals with the development of a horizontally integrated energy system, which consists of a reversible fuel cell stack unitizing both functions of electrolysis and electric power generation and a metal hydride device utilizing an energy storage function. The proposed energy system here is sure to become a fruitful technical option for the load-leveling of electricity in commercial building facilities. Moreover, it is possible for this energy system to innovate the energy performance such as not only to eliminate the mismatch between energy supply and demand but also to improve the robustness for any energy shortage in multilateral and decentralized users.
