Micro-tube type direct-carbon solid oxide fuel cell stack based on biomass charcoal fuel

Abstract

The invention discloses a micro-tube type direct-carbon solid oxide fuel cell stack based on biomass charcoal fuel; the micro-tube type direct-carbon solid oxide fuel cell stack comprises a single micro-tube type solid oxide fuel cell, biomass charcoal, a reaction chamber, a heat preservation layer, a stainless steel net, a thermocouple and an igniter. On the basis of the single micro-tube type solid oxide fuel cell, single cell integration is carried out, so that the micro-tube type direct-carbon solid oxide fuel cell stack has the characteristics of the single-chamber solid oxide fuel cell,however, a cathode and an anode do not need to be sealed and are only simply isolated, so that the sealing cost is saved, and meanwhile, the performance of the cell is improved; under the condition ofno external heat source, the heat generated by combustion of the biomass charcoal fuel is used for maintaining the high temperature required by working of the cell, so that the smooth starting and working of the cell are ensured; and the biomass charcoal adopted by the fuel cell stack is obtained by simply carbonizing biomass, wherein the biomass is rich in reserves and high in energy density, and can be directly combusted to obtain heat energy; and therefore combined heat and power generation can be realized, and the advantages of being green and environment-friendly, high in energy conversion efficiency and the like are achieved.

Description

technical field [0001] The invention relates to a microtube type solid oxide fuel cell directly using biomass charcoal fuel, in particular to a microtube type direct carbon solid oxide fuel cell group based on biomass charcoal fuel. Background technique [0002] Biomass is generally considered to be plants or plant derivatives, and is a renewable energy source that converts solar energy into chemical energy through photosynthesis. Since plants are able to capture the greenhouse gas CO in the atmosphere through photosynthesis 2 , therefore, biomass is actually a carbon-neutral resource. Every year, the biomass energy obtained by plants on land from solar energy is 3-4 times the energy demand of human society. Biomass is gradually becoming a sustainable green new energy and plays an important role in alleviating the global energy crisis. Therefore, it is imperative to develop efficient and clean biomass energy conversion technology. [0003] Solid oxide fuel cell (SOFC) is ...

Problems solved by technology

At present, hydrogen is the most commonly used fuel for SOFC, but hydrogen is a secondary energy source that cannot be directly obtained from nature, and has problems such as high cost, low volumetric energy density, and poor storage and transportation safety.
