Abstract :
It is difficult to repair equipment in a short time after a strong earthquake. Therefore, the power supply to shelters becomes problematic. To solve this problem, a small-scale power system without being dependent on commercial power supplies is needed. We experimentally investigated a power supply system that includes photovoltaic and fuel cells to solve the above-mentioned problem. In this paper, we discuss an efficient operational scheme of the system based on measurement results. We also examined the use of the battery. By effectively using the amount of generated electricity from the photovoltaic cell by using the battery, the fuel cell was able to reduce generation quantity.
