Technologies for the load-leveling of electricity do not directly contribute to the reduction of CO_2 emission which is now the critical political issue in development in the energy field. Though lowering of the load factor is inevitable from a natural feature and a socio-economic activity of Japan, it is a great social loss, considering the operation time of the large-scaled centralized power stations. In this development, we aim at the preparing the technical alternative for the load-leveling and pioneering the new field for hydrogen energy uses in the near future. Here we describe the test fabrication of an reversible cell with enlarged-electrode area to prospect to the technical feasibility of kW-class cell stack and the system integration among a water electrolysis, a hydrogen storage and a fuel cell to optimize both functions of co-generation and energy storage.
