Embodiment 1

[0069] Using the vertical stacking of 5 electric stacks in this application, compared with the tiled arrangement, saves the space of the projected area of ​​4 electric stacks, and the electric stacks are used for power generation experiments, 32Nm 3 / h Air enters, the stack inlet temperature is 650°C-700°C, the air enters the manifold air inlet, manifold air inlet, first internal channel and manifold air outlet sequentially through the air delivery connecting pipe located on the side of the stack The cathode of the stack, the surface of the cathode adsorbs oxygen, and the catalytic effect on the surface of the cathode makes the O 2 Gain electrons and become O 2- , O 2- Diffusion to the anode surface; 20L / min, stack inlet temperature 650°C-700°C, methane gas enters the manifold gas inlet hole, manifold gas inlet, second internal channel and The manifold gas outlet enters the anode of the stack, and O 2- A reaction occurs, and the lost electrons return to the cathode through ...

Abstract

The invention provides a manifold of a solid oxide fuel cell stack and a solid oxide fuel cell comprising the manifold. For an electric pile with the air inlet and the air outlet formed in the bottom,due to the application of the manifold, the air inlet and the air outlet of the electric pile can be led out to the side face of the electric pile from the bottom, all air paths of the electric pileare connected in parallel through the connecting pipe fittings, and therefore, the multiple electric piles are stacked in the height direction, the system arrangement is optimized, and the space utilization rate is increased.

Description

technical field [0001] The invention belongs to the field of solid oxide fuel cells, in particular to a manifold of a solid oxide fuel cell stack and a solid oxide fuel cell including the same. Background technique [0002] A fuel cell is a power generation device that directly converts the chemical energy in fuel and oxidant into electrical energy. The difference from a conventional battery is that the fuel and oxidant are not stored inside the battery, but from an external supply, that is, as long as it is continuously supplied Fuel and oxidant can generate electricity continuously. There are many types of fuel cells, which are mainly divided into the following types according to different electrolytes: alkaline hydrogen-oxygen fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, proton exchange membrane fuel cells and solid oxide fuel cells (Solid Oxide Fuel Cells) Fuel Cell, referred to as SOFC). Compared with other types of fuel cells, SOFC has many un...
