Abstract

The invention relates to an agricultural waste fuel cell. The agricultural waste fuel cell is characterized by comprising a positive electrode side composition material, a positive electrode circulation system, a proton exchange membrane, a negative electrode side composition material and a negative electrode circulation system, wherein the proton exchange membrane is placed between the negative electrode circulation system and the positive electrode circulation system; the positive electrode side composition material is stored in the positive electrode circulation system; the negative electrode side composition material is stored in the negative electrode circulation system; the materials on the two sides are isolated by the proton exchange membrane; the positive electrode side composition material transfers the carried electrons to an external circuit through the positive electrode circulation system; and the proton exchange membrane is combined with the negative electrode side composition material which is pumped through the negative electrode circulation system and external circuit electrons to generate water. By virtue of the agricultural waste fuel cell provided by the invention, the chemical energy of the organic matters in the agricultural waste can be converted into electric energy directly and efficiently at a low temperature; and meanwhile, the agricultural waste fuel cell has the advantages of environmental protection, high electric energy output power density and high electrochemical efficiency.

Description

technical field [0001] The invention belongs to the field of direct liquid catalytic fuel cells, and specifically relates to an agricultural waste fuel cell, which directly converts biomass energy in agricultural waste into electric energy at low temperature, and has the advantages of environmental protection, high output power density of electric energy, and high electrochemical efficiency The advantages. Background technique [0002] Agricultural waste is the organic material discarded in the process of agricultural production, mainly containing cellulose, hemicellulose, lignin, soluble sugar and protein. my country is a large agricultural country, and agricultural waste has great potential for resource utilization. Taking straw as an example, my country can produce hundreds of millions of tons of straw every year, and straw resources are very rich. The resource utilization of crop straw can not only increase farmers' income, but also reduce environmental pollution and e...
