Abstract

The invention discloses a liquid circulation antimony anode tube type direct carbon solid oxide fuel battery electric stack system and a preparation method of the liquid circulation antimony anode tube type direct carbon solid oxide fuel battery electric stack system, and belongs to the field of a fuel battery. The battery electric stack system comprises a battery electric stack, an antimony oxide collecting pool, a fuel pool and a fuel loading device, wherein the top of the battery electric stack is provided with a battery electric stack outlet; the bottom of the battery electric stack is provided with a battery electric stack inlet; the top of the antimony oxide collecting pool is provided with an antimony oxide collecting pool inlet communicated with the battery electric stack outlet; the bottom of the antimony oxide collecting pool is provided with an antimony oxide collecting pool outlet through which antimony oxide flows out; the top of the fuel pool is provided with the fuel loading device; meanwhile, the top of the fuel pool is also provided with a fuel pool inlet communicated with the antimony oxide collecting pool outlet; the bottom of the fuel pool is provided with a fuel pool outlet through which antimony obtained through being reduced by fuel flows out; the fuel pool outlet is communicated with the battery electric stack. The invention also discloses a preparation method of the battery electric stack system. The battery electric stack system has the advantages that the solid-state carbon fuel can be conveniently and directly loaded, and in addition, the liquid-state antimony anode cannot be poisoned or polluted.

Description

technical field [0001] The invention belongs to the field of clean energy fuel cells, and more specifically relates to a liquid circulation antimony anode tubular direct carbon solid oxide fuel cell stack and a preparation method thereof. Background technique [0002] In today's society, the energy crisis has become a worldwide issue. The currently widely used fossil energy is non-renewable, and the rapid development of society leads to a large amount of energy consumption, which makes such traditional energy increasingly scarce. At the same time, the environmental pollution caused by the combustion of fossil energy has brought serious harm to human life. Human beings urgently need energy technologies that are more advanced, more efficient, more widely sourced, and more convenient to use. In this context, it has become a worldwide consensus to develop reliable and environmentally friendly energy sources, reduce the pressure on traditional fossil energy sources, and adopt c...
