The invention discloses a hydrogen supply discharge protection system of a fuel cell in the technical field of fuel cells. The system comprises fuel cell modules, an electric quantity monitoring module, a conversion connection module and a conversion control module, wherein the electric quantity monitoring module, the conversion connection module and the conversion control module are respectivelyconnected with each group of fuel cell modules; the fuel cell module is used for converting chemical energy into electric energy; the electric quantity monitoring module is used for monitoring the residual electric quantity condition of the fuel cell and sending the residual electric quantity information to the conversion control module and the conversion connection module; and the conversion connection module is connected with an energy leading-in module. Power supply for use of an energy consumption module is realized by utilizing a parallel replacement type power supply and discharge mode of multiple groups of fuel cell modules, so that the fuel cell modules can be effectively protected, and the phenomenon that the fuel cell is damaged to different degrees due to the fact that the fuelcell supplies hydrogen and overdischarges simultaneously is avoided.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to a hydrogen supply discharge protection system for fuel cells. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; Transmission parts, so there is no noise material, and the harmful gas emitted is very little; sound pollution. It can be seen that from the point of view of saving energy and protecting the ecological environment, fuel cells are the most promising power generation technology. [0003] In the process of using the existing fuel...
