<p> The results of a measurement survey of PEFC installed in detached houses in Fukuoka City are shown in this paper. The purpose of this measurement survey was to collect the measurement data of fuel cells that are practically used in households. This measurement data is used for simulation programs of PEFC and other fuel cells for residences and the research concerning of examination method of the fuel cells for residences based on industrial standard.</p><p> At first, the purpose and background of this research are shown. Since commercial sales began in 2009, the development and dissemination of the fuel cells for residences have progressed. However, there are only a few case examples of measurement surveys targeting recent model specifications and the relationship among electricity usage, hot water usage and the power generation amount of fuel cells has not been researched enough. A detailed measurement survey of relatively new PEFCs that were purchased around 2013 was conducted and the measurement data were collected.</p><p> Secondly, the outline of the measurement survey, the characteristics of equipment specification of fuel cells that are measured in this paper, and the definition of evaluation items used in this paper are shown. The households subjected for the survey in this paper have introduced Home Energy Management System (HEMS), so they can obtain electricity usage, city gas usage and the power generation amount of fuel cell at hour intervals. These data are totaled, and the life schedule of each household is confirmed.</p><p> Then, the data that were obtained in this research are totaled and the analyses and discussions concerning the evaluation items shown in chapter 2 were performed. The catalog spec of the measured device shows that the efficiency of power generation is 36% by HHV conversion and that of heat rejection is 51%; however, Usage end, the efficiency of power generation of household-I was 35%, that of household-II was 30%, and the heat rejection of household-I was 41%. It was also found that the energy of about 0.4kWh is consumed each day for the start and stop of power generation. This is equivalent to 5-10% of the power generation amount. Sometimes a power generation contribution rate becomes low because the changes of power generation amounts in the fuel cell cannot follow the small fluctuations of electric power usage. In many cases in past research, the average value of the interval of about 1-30 minutes is used as load data to be input. However, it was found that the calculation time interval should be 10 seconds or less for accurate estimation. Finally, the findings obtained through the contents of this paper and the tasks in the future are organized.</p>
