[0019] Hereinafter, embodiments of the present invention will be described based on the drawings. figure 1 It is a block diagram showing the configuration of the fuel cell power generation system 100 according to the first embodiment of the present invention. Such as figure 1 As shown, the fuel cell power generation system 100 includes: a fuel cell 11 including a positive electrode (cathode) 11a and a negative electrode (anode) 11b; air; the air heating heat exchanger 13 (heat exchange part), which heats the air sent from the first air blower 12; the first fuel pump 14, which supplies fuel such as hydrocarbon fuel to the negative electrode 11b of the fuel cell 11 and a fuel reformer 15 that reforms the fuel sent from the first fuel pump 14 through the fuel gas flow path L1 to supply to the negative electrode 11 b.

[0020] It is further provided with: a fuel circulation blower 17 which circulates the fuel gas discharged from the negative electrode 11b to the fuel reformer 15...

[0062] Next, a fuel cell power generation system according to a second embodiment of the present invention will be described. Figure 6 It is a block diagram showing the configuration of a fuel cell power generation system 100a according to the second embodiment. Such as Figure 6 As shown, in the second embodiment, compared with the fuel cell power generation system 100 of the aforementioned first embodiment, it is different in the following respects: a third air blower 32 (temperature adjustment part, temperature adjustment unit) is provided instead of the fuel cell power generation system 100 The positive pole 11a of 11 is connected to the burner 23 . That is, in Figure 6 In the fuel cell power generation system 100a shown, it is possible to introduce unheated air sent from the third air blower 32 into the oxidizing gas supply port of the positive electrode 11a.

[0063] In addition, in the fuel cell power generation system 100 according to the second embodiment, the ai...

Abstract

A fuel cell power generation system according to an embodiment of the present invention comprises: a fuel cell (11) which generates electricity upon the supply of an oxidation gas and a fuel gas; and a temperature control unit (23, 32, 33) which controls the temperature of the oxidation gas to be supplied to an oxidation gas inlet of the fuel cell (11). When the output requirement for the fuel cell (11) is high, the temperature control unit is controlled so as to increase the temperature of the oxidation gas to be supplied to the oxidation gas inlet to a higher temperature than a temperature required when the output requirement is low. In this manner, when the output requirement for the fuel cell (11) is high, the driving temperature for the fuel cell (11) can be increased to a higher temperature than a temperature required when the output requirement is low.

Description

technical field [0001] The present invention relates to a fuel cell power generation system that adjusts the temperature of a fuel cell to generate power according to output requirements and a control method thereof. Background technique [0002] Japanese Unexamined Patent Publication No. 2003-115315 (Patent Document 1) and Japanese Unexamined Patent Publication No. 2004-349214 (Patent Document 2) disclose a fuel cell power generation system in which the positive electrode ( The temperature of the oxygen supplied by the cathode) keeps the temperature of the fuel cell substantially constant (for example, ±10° C.). [0003] In Patent Document 1, the reaction temperature is limited to ±10° C., so the output of the fuel cell is limited, and the controllable power generation output range cannot be expanded. For example, consider a case where a fuel cell power generation system is mounted on a vehicle to provide running energy of the vehicle. In this case, during normal operatio...
