Abstract

In recent years, energy-generating devices such as residential use fuel cell cogeneration systems (FCCGS) have been spreading. A solid polymer electrolyte fuel cell (PEFC), which is a type of FCCGS, determines the amount of power generation and power generation time according to the demand for electricity and hot water supply in houses. Therefore, residents' lifestyle influences a PEFC's load following speed and efficiency. However, there are few actual surveys of household electricity and hot water supply demand, and we haven't fully grasped factors that affect them. Therefore, we aim to acquire home electricity and hot water usage habits that affect PEFC operation by measuring detailed electricity and hot water supply demand in 10 houses in Japan. In addition, we also conducted a questionnaire survey for the households and analysed the influence of resident's behaviour on demand for electricity and hot water supply. We can't see instantaneous changes in the amount of PEFC generated based on hourly data, so we measured the electricity consumption of the entire house and the electricity consumption and hot water consumption of each household appliance every 2 seconds. In this report, we analysed the usage habits of home appliances.
