Power generation system of low-purity hydrogen fuel cell

Abstract

The invention relates to the technical field of hydrogen fuel cells, in particular to a power generation system of a low-purity hydrogen fuel cell, which comprises a frame, and a fuel cell engine, a formic acid storage tank, a reaction kettle, a gas storage tank, an air compressor, an air humidifier, a DC / DC converter, an inverter and a lithium battery pack are respectively mounted in the frame through bolts. Formic acid in a formic acid storage tank is pumped into a reaction kettle and reacts under the action of a catalyst to generate mixed hydrogen, the mixed hydrogen enters a gas storage tank, gas in the gas storage tank is fed into a fuel cell engine, and generated electric energy is converted by a DC / DC converter and is respectively conveyed to an inverter and a lithium battery pack; the current passes through the inverter to drive the driving motor to operate, and the current converted by the DC / DC converter can be stored in the lithium battery pack for standby application, so that the lithium battery pack can be discharged when storing the electricity generated by the fuel cell, and the electricity-electricity hybrid power of the electric vehicle is well realized.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a power generation system of a low-purity hydrogen fuel cell. Background technique [0002] Hydrogen fuel cells are batteries that store energy using the chemical element hydrogen. The basic principle is the reverse reaction of electrolysis of water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to the cathode through the external load. [0003] Chinese Patent No. CN108123162B provides a fuel cell power generation system using liquid hydrogen as fuel, especially a proton exchange membrane fuel cell power generation system, including a proton exchange membrane fuel cell module, a liquid hydrogen storage tank, a buffer tank, a water tank, a heat exchanger, Control valve, radiator, circulating water pump, circulating water pipeline, monitor...
