Study on Hybrid Utilization of Renewable Energy and Fuel Cell for Residential Energy System : Part 3-Experiments and analyses on hybrid system using solar energy and fuel cell

Abstract

This paper constitutes Part 3 in the series of studies on hybrid utilization of renewable energy and a fuel cell for a residential energy system. First, field experiments on the electric power and domestic hot water supply system using both solar energy and the fuel cell were carried out. The primary energy reduction rate to a conventional system reached 46.6%. Second, the hybrid system on the electric power and domestic hot water supply was analyzed for the residential energy system both in Sapporo and Tokyo. It was clarified that the optimum capacity of the fuel cell consisted for approximately 1kW in Sapporo.
