Description
Technical Field
The utility model belongs to the technical field of fuel cell, specifically speaking relates to a fuel cell thermal management system.
Background
The metal fuel cell takes metal as a cathode reactant; oxygen in the air is a positive electrode reactant; a special type of fuel cell in which an aqueous alkaline solution is used as the electrolyte. Because the energy density is high and the metal resources are rich, for example, metals such as zinc, magnesium, aluminum and the like can be used as raw materials, and the energy density is applied to metal fuel cells, so that the application prospect is wide. The method is particularly applied to the market of long-term standby power supplies.
The metal fuel cell used as a standby power supply needs to be kept in a standby state for a long time due to the particularity of the application scene, and needs to be started immediately in an emergency and ensure stable output. Because the metal fuel cell can achieve the best output effect only when the electrolyte is operated within a certain temperature range, the temperature of the electrolyte is too low, the reaction rate of the cell is slow, and the output voltage is lower than a rated value. And as the chemical reaction continues, the temperature of the electrolyte gradually rises, and the output voltage of the battery gradually reaches a rated value, so that the response speed of the battery system is influenced. Therefore, first, the initial temperature of the metal fuel cell electrolyte is maintained within the optimum temperature range, and the metal fuel cell can quickly reach the rated voltage output. Secondly, a large amount of heat is continuously generated in the discharging process of the metal fuel cell, and when the temperature reaches a certain temperature, the heat is radiated by the aid of the radiating device to ensure that the system can stably operate, but if the dissipated part of heat is not well utilized, the energy is wasted. Based on the situation, a set of reasonable thermal management system needs to be designed, so that the performance and stability of the metal fuel cell are improved, and the heat utilization efficiency of the metal fuel cell is also improved.
For example, chinese patent publication No. CN104716364B discloses that a metal fuel cell is normally started under low temperature conditions by using two methods, namely short-circuit heating and chemical heating. Namely, a method of preparing high-concentration KOH electrolyte on site is used for obtaining hot electrolyte and heating the battery, or the battery is heated by utilizing the fact that the anode and the cathode of the battery are connected to realize internal short circuit and generate heat. However, the system is complex, and large energy consumption is generated, so that the service life of the fuel cell is shortened, the heating time and temperature cannot be accurately controlled, and potential safety hazards are easily caused.
