Embodiment 1

[0074] Embodiment 1: Heating part, including burner and U-shaped heating tube

[0075] The burner is made of copper material. Such as Figures 12 to 14 with Figure 10 As shown, because the tail gas final discharge port 57 of the heating tube of the present invention is on the top of the SOFC comprehensive performance experiment device, the burner does not have the tail gas influence of the heating tube at the primary combustion air inlet 4 and the secondary combustion air inlet 6. As a result, the quality of the primary and secondary combustion air is improved (increased oxygen content). At the same time, the thermal efficiency of the burner is also improved.

[0076] Such as Figure 13 with Figure 11 As shown, the cathode fuel chamber 15 in the SOFC working area of ​​the present invention is integrated into a common cathode fuel chamber. The cathode fuel chamber 15 is made of alumina material. The common cathode fuel chamber 15 makes the temperature distribution in t...

Embodiment 2

[0078] Example 2: Closed SOFC working area

[0079] Closed SOFC workspace such as Figure 11 As shown, the upper and lower sides of the SOFC working area 11 are a U-shaped heating tube 21 with a left opening and a U-shaped heating tube 25 with a right opening, a total of eighteen U-shaped heating tubes, and a connecting piece with a left opening 24 and the connecting piece 28 of the opening on the right side, a total of eighteen connecting pieces surround the closed SOFC working area 11 around. The U-shaped heating pipe 21 and the connecting piece 24 etc. of the opening on the left side are all made of alumina material. Moreover, heat-resistant materials are sealed between the heating pipes and between the connecting parts and the connecting parts. The cathode fuel chamber 15 around the SOFC in the SOFC working area 11 is also made of alumina plate and sealed. The space between the cathode fuel chamber 15 outside the SOFC tube 16 and the casing 32 is filled with a high temp...

Embodiment 3

[0082] Embodiment 3: the control of the flow rate and flow rate of fuel

[0083] For the control of fuel flow and velocity, see Figure 7 , Figure 9 with Figures 12 to 14 , the present invention has six anode fuel input ports 66, 67, 68, 69, 70, 53, and one cathode fuel at the cathode fuel input port 55, which enters the SOFC working area through three different paths at the above seven fuel input ports 11.

[0084] The first path is the three-way anode fuel input port 66, 67, 68, respectively connected to the corresponding anode fuel pressure gauge 47*6, and then respectively connected to the corresponding anode fuel flow meter 50*6, the anode fuel input port 66, 67, 68 are connected with the corresponding anode fuel pressure gauge 47*6 and the corresponding anode fuel flowmeter 50*6 respectively with stainless steel pipes. The anode fuel adjustment knob 84*6 on the anode fuel flowmeter 50*6 can control the anode fuel input flow and flow rate. After the three-way anode...

Abstract

The invention relates to a solid oxide fuel cell (SOFC) comprehensive experiment apparatus which belongs to the technical field of SOFC power generation systems. The SOFC comprehensive experiment apparatus comprises a heating part, an SOFC working region, a fuel gas supply part and a fuel gas reforming part; SOFC pipes (16) are all in angled inclination with the plane and adopt a public cathode fuel chamber (15); a heating pipe (9) is in a U shape, and a tail gas outlet is arranged at the upper part of the heating pipe; and six groups of SOFC pipes (6) are respectively used for controlling the input flow quantity and the flow velocity of an anode fuel, wherein three groups of SOFC pipes (6) are subjected to low-temperature reforming, high-temperature reforming and high-temperature preheating, and the other three groups of SOFC pipes (6) are subjected to high-temperature preheating. In the invention, the tail gas from the heating pipe has no influence on the combustion effect of a combustor; the temperature fields of the SOFC working region are evenly distributed; the flow quantity and the flow velocity of the cathode fuel are uniform; and the SOFC comprehensive experiment apparatus is suitable for test comparison of SOFC performances in scientific researches and experiments.

Description

technical field [0001] The invention belongs to the technical field of a solid oxide fuel cell (SOFC) power generation system, and particularly relates to a SOFC comprehensive experimental device used in scientific research or teaching. . [0002] The SOFC comprehensive experimental device is compared with the SOFC power generation system. What they have in common are: the operating temperature of SOFC, the anode fuel, the cathode fuel, the basic mechanism and working principle of the fuel cell, etc. Their differences are: SOFC is miniaturized (miniature), and the installation and disassembly of SOFC should be very convenient, because SOFC is miniaturized (micro) and the fuel supply is small, so an independent heating device is required.
