<P>PROBLEM TO BE SOLVED: To provide a cogeneration system which displays the lifetime of the constituent part of the cogeneration system and can be stably operated by replacing components beforehand. <P>SOLUTION: This is the cogeneration system which generates electricity and heat from a supplied fuel by a fuel cell unit 10 as a cogeneration device, and outputs electricity being supplied to a commercial power supply 1 and outputs heat. The system furthermore comprises an arithmetic unit 42 and a display device 44, and the arithmetic unit predicts the lifetime of the constituent part such as a desulfurization filter 17A and a water filter 17B and displays the lifetime by a component replacement display part 45 of the display device. The lifetime is predicted based on the accumulation operating hour and/or number of starting of the fuel cell unit, and the predicted lifetime against the assumption lifetime for each constituent part is displayed by a level as a remaining lifetime by a lifetime gauge 46 of the display device. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
