The invention provides a biomass liquid flow fuel cell system, which effectively solves the technical problems of excessive energy consumption, low power generation efficiency, low recycling utilization rate and easy deactivation of catalyst of the existing fuel cell.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a biomass liquid flow fuel cell system. Background technique [0002] In recent years, the rapid development of the world economy has led to excessive consumption of fossil energy, resulting in a series of problems such as global resource shortage, environmental pollution and climate deterioration. my country's total energy consumption is large, growing rapidly, and demanding, and many energy sources are still heavily dependent on foreign countries. Therefore, it is necessary to promote my country's energy transformation, large-scale development and large-scale allocation of clean energy. Biomass resources are a clean resource with wide sources, abundant reserves, renewable and low pollution. Electric energy is an economical, practical, clean and easy-to-control and convertible energy form. Therefore, the direct conversion of biomass to electric energy is more and more more ...
