FUEL CELL POWER GENERATION APPARATUS

1 . A fuel cell power generation apparatus for which maintenance is performed, comprising:

an installation environment information inputting section which inputs installation environment information of the fuel cell power generation apparatus;

a notification device which notifies that maintenance of the fuel cell power generation apparatus should be carried out, at a notification time set before a maintenance time of the fuel cell power generation apparatus; and

a controller configured to set a first period between the maintenance time and the notification time based on the installation environment information input by the installation environment information inputting section;

wherein the installation environment information inputting section inputs as the installation environment information, at least one of a signal input by a temperature detector disposed at an installation location of the fuel cell power generation apparatus, a signal input by a temperature detector disposed at a water supply passage connecting a water supply source to the fuel cell power generation apparatus; position information of a position at which the fuel cell power generation apparatus is installed, elevation information of an elevation at which the fuel cell power generation apparatus is installed, maintenance company information indicating a degree of easiness with which a maintenance company carries out the maintenance; and a special period derived based on an average air temperature and an average humidity for each predetermined time period in an environment in which the fuel cell power generation apparatus is installed.

2 . The fuel cell power generation apparatus according to claim 1 , further comprising:

an operation amount obtaining section which obtains an operation amount of the fuel cell power generation apparatus;

wherein the controller is configured to specify the maintenance time based on the operation amount.

3 . The fuel cell power generation apparatus according to claim 2 ,

wherein the operation amount obtaining section determines the operation amount based on at least one of:

an accumulated power generation time of the fuel cell power generation apparatus, an accumulated power generation amount of the fuel cell power generation apparatus, and an accumulated number of times of power generation of the fuel cell power generation apparatus;

a time that passes after the fuel cell power generation apparatus is installed;

an accumulated energization time for which at least either one of the controller and an auxiliary device of the fuel cell power generation apparatus is supplied with electric power;

an accumulated operation time and an accumulated number of times of operation of a device constituting the fuel cell power generation apparatus; and

an accumulated heat supply amount of the fuel cell power generation apparatus.

4 . The fuel cell power generation apparatus according to claim 1 ,

wherein the controller is configured to set the first period longer, when it is determined that the maintenance time falls into a special period when it is more difficult to carry out the maintenance than in another period, based on the installation environment information, than when it is determined that the maintenance time does not fall into the special period, based on the installation environment information.

5 . The fuel cell power generation apparatus according to claim 4 ,

wherein the controller is configured to set the first period such that the notification time comes before start of the special period, when it is determined that the maintenance time falls into the special period.

6 . The fuel cell power generation apparatus according to claim 1 ,

wherein the controller is configured to set the first period longer, when it is determined that an installation location of the fuel cell power generation apparatus falls into a special area where it is more difficult to carry out the maintenance than in another area, based on the installation environment information, than when it is determined that the installation location of the fuel cell power generation apparatus does not fall into the special area, based on the installation environment information.
