The invention provides a fuel cell with an energy recycling function and relates to the technical field of fuel cells. The fuel cell with an energy recycling function comprises an electric pile. A gasoutlet of the electric pile is communicated with a heat recycling system, and a gas outlet of the heat recycling system is communicated with a hydrogen recycling system. According to the invention, the gas outlet of the electric pile is communicated with the heat recycling system to recover a large amount of heat generated in the fuel cell reaction process; and meanwhile, the gas outlet of the heat recycling system is communicated with the hydrogen recycling system to recover unreacted hydrogen in the reaction process of the fuel cell, so that the problem of energy dissipation of the fuel cell is jointly solved, and the energy efficiency of the fuel cell is improved.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell with energy recovery and utilization. Background technique [0002] With the excessive exploitation and use of underground mineral resources such as petroleum and coal mines, their reserves are gradually depleted, and environmental pollution is becoming more and more serious. Over the years, various countries have been committed to finding energy utilization methods with high energy utilization efficiency and no pollution to the environment, and fuel cells, as a new type of energy, have gradually entered people's field of vision. [0003] A typical fuel cell is a hydrogen-oxygen fuel cell, which converts chemical energy into electrical energy through the electrochemical action of hydrogen and oxygen. Compared with the traditional fuel power generation method, the reaction result of the fuel cell will produce very little carbon dioxide and nitrogen oxides, the by-p...
