| Abstract |
Energy used at home accounts for about 20% of the total energy used in the country, so efficient use of electricity used at home is very important for national energy conservation and reduction of pollution factors. Therefore, among the distributed fuel cells, the household fuel cell (RPG: Residential Power Generator) that is receiving the most attention is expected to be able to solve heating and cooling in the house and use electricity in 10 years without external help. In general, electric energy production always accompanies the production of heat, but the transport of heat for heating is very difficult. In the case of conventional power generation, electricity is generated from large-scale power generation and hot water is received from a boiler at home, whereas the fuel cell system has the advantage of being able to use heat because it produces electricity and heat directly at home. Therefore, the home is the best place to produce and consume heat and electricity at the same time. It is the most ideal place to use the supplied city gas to produce and use heat and electricity using a locally installed small fuel cell power generation system with low exhaust gas and no noise. It could be a household energy system. In this paper, the operation characteristics of a home fuel cell system for distributed power control are verified by designing and manufacturing a fuel cell simulator, a DC/DC step-up converter, and an inverter suitable for a home cogeneration system. |
