Embodiment approach 2

[0051] Next, the fuel cell system in Embodiment 2 will be described below. image 3 It is a diagram showing an example of a schematic configuration of a fuel cell system according to Embodiment 2. exist image 3 In the case of the figure 1 Components that are the same as those shown in the schematic diagrams are given the same symbols and their descriptions are omitted.

[0052] like image 3 As shown, the fuel cell system of the present embodiment has basically the same configuration as the fuel cell system of the first embodiment. However, it differs from Embodiment 1 in that the hydrogen generator 2 is provided with a CO remover 19 for reducing carbon monoxide in the hydrogen-containing gas generated by the reformer 3 through an oxidation reaction, and a third stream The fourth flow path 18 through which the oxidizing gas of the CO remover 19 flows is branched from the path 16 .

[0053] The CO remover 19 reduces carbon monoxide in the hydrogen-containing gas generate...

Deformed example 1

[0060] Next, Modification 1 of the fuel cell system of Embodiment 2 will be described below. Figure 4 It is a diagram showing an example of a schematic configuration of a fuel cell system according to this modification. like Figure 4 As shown, the fuel cell system of this modified example is characterized in that a third on-off valve 20 is provided on the third flow path 16 upstream of the branching part branching to the fourth flow path 18, and by opening this third on-off valve The valve 20 thus connects the third flow path 16 and the fourth flow path 18 . Furthermore, when the oxidizing gas is supplied from the oxidizing gas supplier 15, the third on-off valve 20 is opened.

Deformed example 2

[0062] Next, Modification 2 of the fuel cell system of Embodiment 2 will be described below. Figure 5 (a) to (c) are diagrams showing an example of a characteristic schematic configuration of a fuel cell system according to the modification. The fuel cell system of this modified example is different from the fuel cell system of Modified Example 1, and is characterized in that it includes a third on-off valve 20 that connects / blocks the third flow path 16, and a fourth on-off valve that connects / blocks the fourth flow path 18. On-off valve 21. Regarding the concrete structure of the 3rd on-off valve 20 and the 4th on-off valve 21, as Figure 5 (a) ~ (c) shown.

[0063] exist Figure 5 In (a), the third on-off valve 20 is provided on the third flow path 16 on the downstream side (on the side of the first flow path 10 ) of the branch portion branching to the fourth flow path 18 . The fourth on-off valve 21 is provided on the upstream side (on the side of the oxidizing gas su...

Abstract

Disclosed is a fuel cell system (100) which comprises: a hydrogen generation unit (2) that includes a reformer (3),a burner (5) that supplies heat to the reformer (3),a fuel cell (1),a first flow channel (10),a second flow channel (8),a third flow channel (16) in which oxidation gas to be supplied to the first flow channel (10) between a branch portion (10a) and the fuel cell (1) flows,a first on-off valve (7a) that is disposed in the first flow channel (10) downstream of a junction portion (10c),a second on-off valve (6) disposed in the second flow channel (8),an oxidation gas supply unit (15) disposed in the third flow channel (16),and a control unit (200) that supplies the oxidation gas to the first flow channel (10) downstream of the junction portion (10c) through the third flow channel (16) by closing the first on-off valve (7a) and opening the second on-off valve (6) at the time of startup and operating the oxidation gas supply unit (15) when hydrogen-containing gas is being delivered from the hydrogen generation unit (2).

Description

technical field [0001] The present invention relates to a fuel cell system in which a small amount of oxidizing gas is mixed into hydrogen-containing gas supplied to a fuel cell, and a method of operating the fuel cell system. Background technique [0002] Figure 8 It is a schematic configuration diagram of a conventional fuel cell system. like Figure 8 As shown, in the conventional fuel cell system 700, means for supplying hydrogen-containing gas required for power generation operation is generally not provided as an infrastructure. Therefore, a hydrogen generator for generating hydrogen-containing gas required for power generation operation is provided. [0003] The hydrogen generator includes a hydrogen generator 2 having a reformer 3, and by performing a reforming reaction in a reforming catalyst in the reformer 3, a raw material containing an organic compound having at least carbon and hydrogen as constituent elements and water This produces hydrogen-containing gas....
