A fuel cell cogeneration system includes a fuel cell module, a heat exchanger, a hot water tank, a circulating water channel, and an oxygen-containing gas supply channel. A circulating water heater for heating water is provided on the circulating water channel. Part of the oxygen-containing gas supply channel is provided in the circulating water heater to thereby allow air flowing through the oxygen-containing gas supply channel to be heated by receiving heat from the circulating water heater.

Provided is a junction boxwith an electric circuit formed by laminating a plurality of resinous plates, wherein a plurality of pole structuresis uprightly formed on a bottom (lower casing) of the junction box so as to be located at a position not overlapping the conductive patternsof the laminated plates and to face a direction of penetrating the plates, in which a plurality of insertion holesis formed in the resinous platesso as to allow the pole structuresto be inserted therethrough, in which the plurality of pole structuresis formed to have different heights, and in which insertion holesare formed in each of the resinous platesso as to allow the pole structuresto be inserted therethrough and to match with the heights of the pole structureshaving different heights.

Junction box

A wiring structure includes a board assembly and pin terminals. In each of pin terminal insertion holes formed in the board assembly, a terminal connection portion electrically connected to a metal foil wire and fitted onto the pin terminal so as to hold the pin terminal is provided in a through-hole of at least one of a plurality of circuit boards forming the board assembly, which forms a part of the pin terminal insertion hole, whereas an insulating sleeve blocking contact between the pin terminal and each of the remaining circuit boards is fitted into through-holes of the remaining circuit boards, which form the remaining part of the pin terminal insertion hole.
