specific Embodiment approach 1

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 1. An electrolyte-supported single-gas chamber solid oxide fuel cell with electrode surfaces perpendicular to each other. It consists of an electrolyte support, an anode and a cathode. The anode and cathode are respectively fixed on two surfaces of the electrolyte support that are perpendicular to each other.

[0009] The manufacturing process of the battery in this embodiment is as follows: 1. Put the electrolyte powder into the mold, press it into a square green body under a pressure of 10-2000 MPa, and sinter it at 1300 ° C ~ 1500 ° C for 4 hours to obtain the electrolyte support Body 1; 2. Evenly coat the prepared anode slurry on a plane of the electrolyte support, sinter at 1150°C~1350°C for 2~4h, and then evenly coat the prepared cathode slurry on The other plane of the electrolyte support body perpendicular to the plane where the anode is located is sintered at 1000° C. to 1200° C. for 2 to 4 hours to obtain the bat...

specific Embodiment approach 2

[0011] Embodiment 2. The difference between this embodiment and the electrolyte-supported single-chamber solid oxide fuel cell with electrode surfaces perpendicular to each other described in Embodiment 1 is that the electrolyte support 1 is a cuboid, cylinder or platform.

[0012] The electrolyte support 1 in this embodiment can also be a trapezoidal platform, and the electrode distribution is as follows: figure 2 shown.

[0013] For different electrolyte support 1 conditions, the specific structure of the battery pack has the following forms:

[0014] combine Figure 5 This embodiment is described. In this embodiment, the anode and cathode of the battery are respectively arranged on the two sides of the block-shaped electrolyte support 1 along one edge to form a group of single cells. The cathodes in the former group of single cells are connected to the anodes in the latter group of single cells through high temperature resistant wires 4 to form a series battery pack of 2...

specific Embodiment approach 3

[0019] Specific embodiment three, combine Figure 1~9 Describe this specific embodiment. The difference between this embodiment and the electrolyte-supported single-chamber solid oxide fuel cell whose electrode surfaces are perpendicular to each other described in Embodiment 1 or 2 is that the cross-sectional shapes of the anode 2 and the cathode 3 are square, round or toroidal.

[0020] This embodiment can meet the needs of batteries with different structures.

Abstract

The invention discloses an electrolyte support single-air-chamber solid oxide fuel battery with mutually vertical electrode surfaces, belonging to an electrolyte support single-air-chamber solid oxide fuel battery and aiming at solving the problems of large ohmic resistance and lower output performance of the traditional coplanar single-air-chamber solid oxide fuel battery with electrolytes distributed on the same plane. The positive pole and the negative pole of the battery are respectively fixed on two mutually vertical planes of an electrolyte supporting body. The invention is suitable forvarious occasions adopting fuel batteries to supply power.

Description

technical field [0001] The invention relates to an electrolyte-supported single-chamber solid oxide fuel cell. Background technique [0002] Single-chamber solid fuel cell (SC-SOFC for short) is a fuel cell with a new structure. It is different from the traditional solid oxide fuel cell (SOFC for short). Selective catalytic to work. The cathode and anode electrodes of the battery are in the same air chamber. In addition to the advantages of high efficiency and environmental protection of the traditional solid oxide fuel cell, it also has the advantages of simple structure, low requirements for sealing, good heat resistance and mechanical shock resistance, and it is easy to realize various small-scale The battery pack design and other advantages. In recent years, it has gradually become a research hotspot in the field of solid oxide fuel cells. [0003] A very important structure in the existing single-chamber solid fuel cell is the same-plane electrolyte-supported single-...
