Embodiment approach 1
[0047] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
[0048] As shown in Fig. 1, the fuel cell power generation system (1) according to this embodiment includes: a desulfurizer (3), a first start-up combustion chamber (4), a pre-reformer (5), and a self-heat exchanger ( 6), internal reforming solid electrolyte fuel cell (7) (hereinafter referred to as fuel cell), burner (9), heat exchanger (11), first to eighth channels (13, 14, 15, 16, 17, 18, 19, 20), the first and second solenoid valves (21, 22), and the first to third blowers (23, 24, 25), etc. And, the first combustor of the present invention is made of the first start-up combustion chamber (4), the reformer is made of the pre-reformer (5), the solid electrolyte fuel cell is made of the fuel cell (7), and the first heat exchanger is made of The self-heat exchanger (6) is constituted, the first combustion gas supplier is constituted by the fourth flow channel (16), a...
Embodiment approach 2
[0148] In the fuel cell power generation system (1) according to this embodiment, combustion gas is supplied to the air chamber before power generation starts.
[0149] As shown in Figure 2, the fuel cell power generation system (1) according to this embodiment includes: a desulfurizer (3), a second starting combustion chamber (8), a pre-reformer (5), a fuel cell (7) , burner (9), heat exchanger (11), 9th to 19th runners (43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 62), 3rd to 19th 6 Solenoid valves (63, 65, 67, 69) and the first to third blowers (23, 24, 25), etc. Furthermore, the second burner of the present invention is constituted by the second start-up combustion chamber (8), and the second combustion gas supplier is constituted by the sixteenth and seventeenth flow passages (57, 59).
[0150] One end (the right end in Fig. 2) of the ninth flow channel (43) is connected with the inlet (3a) of the desulfurizer (3).
[0151] One end (left end) of the tenth channel (45) is con...
Embodiment approach 3
[0209] In the fuel cell power generation system according to the present embodiment, when the fuel cell (7) is activated, air exchanging heat with combustion gas is supplied to the pre-reformer (5) and the air chamber.
[0210] As shown in Figure 3, the fuel cell power generation system (1) according to this embodiment includes: a desulfurizer (3), a third starting combustion chamber (12), a pre-reformer (5), a fuel cell (7) , Burner (9), 1st and 2nd heat exchangers (93, 95), 20th to 29th runners (73, 75, 77, 79, 81, 83, 85, 87, 89, 9 1) , 7th to 10th solenoid valves (97, 99, 101, 103) and 1st to 3rd blowers (23, 24, 25), etc. And, the 3rd burner of the present invention is made up of the 3rd start-up combustion chamber (12), and the oxygen-containing gas supplier is made up of the 21st, the 25th and the 27th flow passage (75,83,87), and the 2nd heat exchanger Consists of a first heat exchanger (93).
[0211] One end (the right end in Fig. 3) of the 20th flow channel (73) is...
