Description
Technical Field
The invention relates to the technical field of fuel cells, in particular to a multi-stage uniform flow field fuel cell.
Background
Energy is an important material basis on which human beings live and develop, and all activities of the human society cannot leave the energy. With the rapid development of economy and the continuous progress of society, the consumption of energy by human beings is continuously increased. The energy demand continues to increase worldwide and the consumption of traditional fossil energy remains dominant. However, traditional fossil energy reserves are limited and some of the energy will be depleted in the coming decades. In addition, in the process of utilizing traditional fossil energy, the problem of environmental pollution is also increasing, and the problems of greenhouse effect, acid rain, ozone layer damage and the like caused by the problem seriously threaten the survival and development of human beings. In the face of serious challenges of energy crisis and environmental protection, finding clean sustainable energy capable of replacing traditional fossil energy is certainly the focus of human research.
At present, solar energy, wind energy, tidal energy, geothermal energy and the like have the advantages of sufficient energy, clean and pollution-free utilization process and the like. However, the energy sources have the problems of intermittency, instability, low efficiency and the like in the utilization process. Fuel cells are receiving much attention because of their advantages such as high energy conversion efficiency, low pollution, and no noise. As a new generation of energy technology, the fuel cell provides a new idea for solving the problems of energy crisis and environmental pollution, and has strategic significance. The fuel cell technology is a novel power generation technology, can directly convert chemical energy existing in fuel and oxidant into electric energy, has the remarkable advantages of high efficiency, no pollution, no noise, high reliability, modularization, quick response to load change and the like, and is considered as an ultimate solution for solving the energy crisis.
The fuel cell mainly comprises an ion exchange membrane, a positive electrode, a negative electrode and a bipolar plate. The Membrane Electrode Assembly (MEA) composed of a cathode electrode, an ion exchange membrane and an anode electrode is a place where electrochemical reaction of the fuel cell occurs. Fuel and oxidant are introduced into the anode and cathode of the cell, respectively. Fuel (e.g. H) passed to the anode2、CH3OH、CH3CH2OH、CO(NH2)2、NaBH4HCOONa, etc.) to release electrons, which flow to the cathode through an external circuit and react with the cathode's oxidant (e.g., O)2、H2O2Etc.) the reduction reaction occurs in combination. While ions migrate through the electrolyte membrane to the cathode (or anode) to form a circuit.
Among the various types of fuel cells, Direct Liquid Fuel Cells (DLFC) have received much attention in recent years due to advantages such as high fuel energy density, convenience in storage and transportation, and the like. The direct liquid fuel cell is a fuel cell using liquid such as methanol, ethanol, urea, sodium borohydride, formate and the like as fuel. Direct liquid fuel cells can be classified into acid direct liquid fuel cells and alkaline direct liquid fuel cells according to the kind of the solid electrolyte membrane.
As a key part of a direct liquid fuel cell, the anode flow field has the functions of conveying fuel, distributing fuel and recovering products, and plays a very key role in the whole operation process of the fuel cell. The current anode flow field of the fuel cell mainly comprises a serpentine flow field, a parallel flow field, a discontinuous flow field, an interdigital flow field and the like, and the anode flow field mainly enters an electrode for reaction through the diffusion effect of fuel flowing on one side of the electrode. In the process, along with the flowing of the fuel in the flow channel and the diffusion reaction in the electrode, the fuel continuously consumes products and continuously enters the flow channel, the concentration of the fuel is gradually reduced, the concentration distribution of the fuel in the electrode is uneven, the electrode reaction efficiency is reduced, and the working efficiency of the direct liquid fuel cell is further reduced.
Therefore, in order to solve the problems of fuel product mixing and uneven fuel concentration distribution in the flow reaction process of fuel cell fuel, a high-efficiency fuel cell with fuel product phase separation and concurrent flow transmission and uniform fuel concentration distribution is in urgent need.
